ATERAL

The 2009 NEESWood Capstone test is the largest full-scale earthquake test

in history. It featured a seven-story, 40' x 60' condominium tower that was

outfitted with Simpson Strong-Tie ® lateral systems products and subjected

to the ground motions equivalent to a 7.5 magnitude quake.

As the leading manufacturer of seismic

holdowns for site-built shearwalls, it

was natural for Simpson Strong-Tie

to apply our expertise to structural

systems that resist lateral forces from

seismic and high-wind events. Our

Wood and Steel Strong-Wall® products

are a result of our research efforts to

improve the efficiency of shearwalls,

as is our Anchor Tiedown System

for multi-story structures.

Our latest addition, the Strong Frame™

ordinary moment frame, rounds out our

lateral-systems offering and provides

specifiers and builders a cost-effective

alternative to site-built moment frames.

All of our lateral systems product

lines allow designers the freedom

to include larger window and door

openings as well as open spaces in

their designs while still meeting

the requirements of the building codes.

There is no other company in the

industry that offers such a wide variety

of lateral systems solutions – solutions

our customers use to make buildings

safer and stronger.

Strong Frame™

Introduction to the Strong Frame™ Ordinary Moment Frame

For years steel moment frames have been a common methodof providing high lateral-force resistance when limited wall

space and large openings control the structural design.Moment frames consist of beams and columns, typicallyconnected by a combination of bolts and welds to formrigid joints. The frames resist lateral loads primarily throughbending in the beams and columns.

Stronger than site-built or factory-built shearwalls, momentframes allow larger openings and smaller wall sections while stillproviding the loads structural designers need. Moment framesare commonly used in applications such as garage fronts, largeentry ways, walls with large, numerous windows, tuck-underparking and great-rooms.

Traditionally, moment frames have been time-intensive to designand labor-intensive to install. Simpson Strong-Tie has taken

these factors into consideration and has created a cost-effectivealternative to traditional frames – the Strong Frame™ ordinarymoment frame.

Use of ordinary moment frames is permitted in Seismic DesignCategories A, B and C without limitations and Seismic DesignCategories D, E and F, subject to the limitations set forth inASCE 7-05 Sections 12.2.5.6, 12.2.5.7 and 12.2.5.8. Ordinarymoment frames may also be combined with other lateral-force resisting systems in accordance with ASCE 7-05 Section12.2.2 and 12.2.3.

Introduction to the Strong Frame™ Ordinary Moment Frame

Pre-designed moment frame solutions:• Designers can choofrom 368 engineered frames, in sizes up to 20 feet wide and19 feet tall, rather than having to spend hours designing oneSolutions provided for wind and seismic areas.

100% bolted connections:• Install frames faster with no fieldwelding required. No need to have a welder on site, or aspecial welding inspector. A standard socket or spud wrenchis all that is required to make the connection.

Pre-installed wood nailers:• Eliminate the need to drill andbolt nailers in the field.

Strong Frame ordinary moment frames are thecost-effective solution for your next project

Frames fit in a standard 2x6 wall:• No thicker walls, noadditional framing or furring required.

Pre-drilled holes for utilities:• 1" diameter holes in the flangesand 3" holes in the column webs simplify the installation ofelectrical and plumbing elements.

Greater quality control:• Frames are manufactured in aproduction environment with comprehensive quality-controlmeasures. Field-bolted connections eliminate questionsabout the quality of field welds. Direct-tension-indicatorwashers included.

Convenient to store, ship and handle:• Unassembled framesare more compact, allowing for easier shipping and fewerdeliveries. And, there are no big pre-welded frames to wrestwith on the jobsite.

Pre designed anchorage solutions:• See pages 38–44.

• New Custom Sizes: Now we offer custom beam lengthsand column heights made to order, ideal for new or retrofitprojects.

• Now Code Listed: Strong Frame Ordinary MomentFrames are now code-listed under the 2006 and 2009 IRC/ IBC (IAPMO ES ER-164). The code listing includes 368 frammodels as well as anchorage solutions. Now it is even easieto specify a Strong Frame moment frame – no calculationpackages are required for the building department (but theyare still available upon request).

Bolt-Tightening Requirements

General Bolt Installation Instructions

All hardware must be protected from dirt and moisture. Do not1.remove hardware from packaging until it is ready for installation.

The performance of bolt assemblies2. (bolt, nut, hardened washerand DTI washer) has been verified through pre-installation verificationtesting. (IMPORTANT: Do not substitute any components.)

Lubrication is critical to proper installation. Do not remove lubricant3. on bolt assemblies or apply additional lubricant.

High-strength bolts which have been fully tightened may only be4.reused if the nut can still be threaded onto the bolt by hand.

The type of joint5. (snug-tight or pretensioned) shall be determined bythe Designer. (See page 17 for more information.)

Snug-Tight Joints

Install a DTI washer under the bolt head, with the protrusions against1.the bolt head. Slide the bolt through the connection holes. Install thehardened washer and nut on opposite side (see Figure 1).

Tighten all bolts to snug-tight condition, making sure the bolt head does2.not turn while the nut is turned (see Figure 2). Snug-tight condition is

the tightness attained by either a few impacts of an impact wrench orthe full effort of a worker with an ordinary spud wrench that brings thebeam end plate and column flange into firm contact. (Little or no orangesilicone from the DTI washer should be visible at this time; see Figure 3).

Pretensioned Joints

Install a DTI washer under the bolt head, with the protrusions against1.the bolt head. Slide the bolt through the connection holes. Install thehardened washer and nut on opposite side (see Figure 1).

Tighten all bolts to snug-tight condition, making sure the bolt head does2.not turn while the nut is turned (see Figure 2). Snug-tight condition isthe tightness attained by either a few impacts of an impact wrench orthe full effort of a worker with an ordinary spud wrench that brings thebeam end plate and column flange into firm contact. Little or no orangesilicone from the DTI washer should be visible at this time (see Figure 3).

Once all bolts are snug-tight, calibrate the DTI washers by fully3.tightening one of the four inside bolts (see Figure 4). Proper installationpretension is reached when the 0.015" feeler gauge can no longer beinserted all the way into the bolt shank at three or more of the fivenotches between the silicon markers (see Figure 5). Remember to makesure the bolt head does not turn while the nut is turned.

Tighten all bolts, starting with the most rigid part of the joint (typically4.the three remaining inside bolts, and then the four bolts above andbelow the beam) (see Figure 4). The proper installation pretension isreached when the amount of squirt from the silicon markers matchesthe washer from the calibration in Step 3. When tightening bolts, makesure the bolt head does not turn while the nut is turned.

Verify that at least four of the silicon markers have squirted at each bolt.5.Completely flattened DTI washers are acceptable.

Connection-Plate Gaps And Finger Shims

The finger shims provided may be used to adjust the connection betweenthe beam end plate and column flange. For a gap of 1 ⁄ 8" or less under thebolt head (see Figure 4) , draw plates together by tightening the bolts untilplates are in firm contact. If the gap exceeds 1 ⁄ 8", shims must be installed.Gaps away from the bolt heads are permitted. If the connection platescannot be drawn together sufficiently by tightening the bolts, additionalshims are required. Total thickness of shims under each bolt head mustnot exceed 1 ⁄ 4". To install shims, loosen connection bolts and slide providedshims around the bolts where necessary. Make sure shims do not protrude

beyond the outer edges of the connection plates, and re-tighten bolts.

Suggested Installation Instructions for Retrofit Applications

Install anchorage into the footing per the Designer’s specifications.1.

Install2. 5 ⁄ 8" heavy hex nuts onto the anchors, lowering them all the waydown to the concrete. These will be used to level the frame.

Place the Strong Frame3. ™ columns onto the anchors so that they sit onthe leveling nuts.

Plumb both columns, and install temporary bracing on each,4.perpendicular to the building line. Install the remaining 5 ⁄ 8" heavy hexnuts, finger-tight against the base plate.

Raise the Strong Frame beam straight up between the two columns5.until the tops of the connection plates are flush. The interior columnwood nailers may need to be removed and replaced after the beam isin place.

Bolt the beam to the columns using6. 7 ⁄ 8" A325 high-strength bolts andwashers (included). DTI washers are also included and should be usedwhere required. Fully tighten the nuts with a wrench, tightening all thebolts on one side of the beam, and then the other. (See page 15.)

Rotate the nuts on the base plate to the top of the anchors and, working7.from side to side, raise the leveling nuts until the moment frame topplate is at proper elevation.

Retrofit Applications

Making sure that all leveling nuts are fully seated against the bottom of8.the base plate, fully tighten the baseplate nuts (½ turn past finger tight).Install non-shrink grout per instructions.

Re-install the ordinary moment frame column wood nailers using9.carriage bolts, if removed.

Strong Frame Ordinary Moment Frame Retrofit ApplicationsThe Strong Frame™ ordinary moment frame is an excellent option for retrofitting a moment frame into an existing structure. And withour new expanded range of standard as well as custom sizes, we can provide a moment frame for practically any field condition. It is theinstaller’s responsibility to safely and adequately temporarily shore the existing structure per OSHA and jurisdictional recommendationsduring the moment frame installation process. Check with the local building department for requirements.

Notes: This schematic is intended to illustrate one option for utilizing Strong Frame™ ordinary moment frame in a soft-story retrofit of a typical tuck-under parking application. Not all detailsfor a complete design are shown, nor is this the only way to accomplish such a retrofit. Structural analysis must be performed by a qualified design professional.

Simplified DesignSimpson Strong-Tie® Strong Frame™ ordinary moment frames are pre-engineered and simplify design for a wide variety of applications:

Beams are designed as unbraced – no beam bracing required within•the span.

Frame designed assuming pinned-base condition.•

Allowable loads applicable to wind and seismic loads – no need to•

convert.

Use in the same manner as any other ordinary steel moment frame –•can be used in vertical and horizontal combinations with other lateral-force-resisting elements in accordance with the IBC and ASCE 7-05.

Designs are based on calculation – no test reports required; easily•adaptable to alternate installations. Calculation packages are availablefor each frame, contact Simpson Strong-Tie, if required.

Details are provided (in this catalog) to adjust the height of the top of•the frame when the frame height does not match the structure.

Details are provided (in this catalog) to allow additional beam and•column penetrations to simplify the installation of utilities.

Frames may be used as an alternative to braced-wall panels required•by the IBC and IRC. For more information, see the Strong Frame“Wall Bracing” section at www.strongtie.com.

Using this Catalog as a Design ToolThe selection of a complete moment frame design solution is easyusing the Strong Frame ordinary moment frame. A step-by-stepdescription of the design process is included in this catalog onpages 19–21, and design examples on pages 48–51 provide furtherinformation. After completing these steps, Designers will have all of theinformation necessary to properly specify the Strong Frame ordinarymoment frame and detail its installation:

Design Information

For additional detailed information on the design and proper use ofStrong Frame ordinary moment frames, see General Notes on page 6and General Instructions for the Designer on page 7.

Bolt Tightening RequirementsIn order for the Strong Frame ordinary moment frame to achieve its ratecapacity, the connection plates must have firm contact and the bolts

must be properly tightened. Bolts shall be tightened in compliance withthe Specification for Structural Joints Using ASTM A325 or A490 Bolts ,published by the Research Council of Structural Connections (RCSC). TDesigner shall specify whether the installation requires snug-tight jointsor pretensioned joints.

For design of structures assigned to Seismic Design Category D, E, or F•pretensioned bolts are required.

For design of structures assigned to Seismic Design Category A, B, or •snug-tight bolts may be used when seismic design is based on R ≤ 3.

For design of structures assigned to Seismic Design Category A, B, or •pretensioned bolts are required when seismic design is based on R > 3

The Direct Tension Indicator (DTI) washers provided with each framemake verification of proper bolt installation easy for both snug-tight a

pretensioned bolts and are recommended for all installations. If the DTwashers are not used in connections that require pretensioned bolts,an alternate pretensioning method must be specified by the Designer,including pre-installation verification testing of the complete fastenerassembly and inspection procedures. For detailed information on theuse of the DTI washers provided, see page 15.

Base Plates and Non-Shrink GroutThe Strong Frame ordinary moment frame has been designed toaccommodate a 1 ½" grout pad below the column base plates in orderto facilitate plumbing and leveling of the frame. Proper performanceof the base connection and anchorage of the frame requires that non-shrink grout with a minimum compressive strength of 5,000 psi be

placed below the column base plates. The thickness of the grout padmay vary based on field conditions, but must be a minimum of ¾" thicand no more than 2" thick. Frame height dimensions throughout thiscatalog are based on a grout thickness of 1 ½" and must be adjusted foother grout pads. The Designer may specify installation of base platesdirectly on concrete (without grout) provided they are set level, to thecorrect elevation, and with full bearing.

Base plate design is based on 5 ⁄ 8" diameter anchor rods, which areincluded with the Simpson Strong-Tie OMFSL and OMFAB anchorageassemblies. Base plate holes are 7 ⁄ 8" diameter to allow for tolerances inplacement of the anchor rods. The Designer must evaluate the effects the oversized hole and provide plate washers with 11 ⁄ 16" diameter holeswelded to the base plate where required.

Strong Frame™

Design Information

Anchorage DesignSimpson Strong-Tie offers pre-engineered anchorage solutions tosimplify the design process. Pages 39–44 provide solutions for bothtension and shear anchorage for all of the Strong Frame™ ordinarymoment frame models.

Tension Anchorage•Anchorage solutions for tension loads provide minimum anchor

rod embedment and footing size. Where additional uplift from windoccurs, Table 1.2 on page 39 may be used to design an anchoragesolution.

OMFSL and OMFAB Anchorage Assemblies•Simpson Strong-Tie offers two different pre-assembled anchorageassemblies. The OMFSL anchorage assembly places the frame flushwith the edge of concrete allowing it to fit into a standard 2x6 wallwithout bump-outs or furring. The OMFAB anchorage assembly withadditional concrete reinforcement is an economical alternative forapplications where 2½” (or greater) edge distance exists.

Flexible Anchorage Solutions•Both Simplified and Detailed options are provided for anchoragedesign in order to allow ease of design and specification as well asrefined design for project-specific load conditions. For simplified

anchorage solutions, after selecting a frame, all that is needed todetermine the required anchorage is the column size and nominalframe height. For cases where more economical anchorage isdesired, Detailed anchorage solutions provide capacities of theanchorage assemblies. Simply use the maximum reactions tabulatedin the allowable load tables for the selected frame, and find therequired anchorage with a capacity that exceeds the reactions. Foreven further economy, select an anchorage solution using reactionscalculated for project-specific loads as described in the footnotes ofthe allowable load tables

Anchorage Design Notes•The steel strength calculations for anchor shear and anchor tensionare per ACI 318-05 and 318-08 Appendix D. Tension and shearanchorage are designed as follows:

Element Code Section

Anchor rod strength in tension ACI 318, D.5.1

Anchor breakout strength in tension ACI 318, D.5.2Anchor pullout strength in tension ACI 318, D.5.3

Anchor rod strength in shear ACI 318, D.6.1

Embedded plate bending strength AISC Chapter F

Concrete shear strength – shear lug AISC Design Guide 1

Concrete shear strength – tied anchorage ACI 318, chapter 10

Anchorage Designs are based on LRFD loads. For designs under the2006 IBC, tension anchorage for seismic loads complies with ACI318-05 Appendix D; design includes application of 0.75 factor onconcrete strengths (Section D.3.3.3) and the strength is governedby a ductile steel element (Section D.3.3.4) or is based on 2.5 xfactored loads (Section D.3.3.5 with modifications contained in 2006IBC section 1908.1.16). For designs under the 2009 IBC, tension

anchorage for seismic loads complies with ACI 318-08 AppendixD; design includes application of 0.75 factor on concrete strengths(Section D.3.3.3), and strength is governed by a ductile steel element(Section D.3.3.4) or is based on 2.5 x factored loads (Section D.3.3.6).

Anchorage designs are based on embedment for tension into thefoundation, while shear design is based on resistance within thecurb or slab. For other conditions, the designer must consider theinteraction of tension and shear concrete failure surfaces.

InspectionsInspection requirements for the Strong Frame ordinary moment frameare no different than for any other ordinary steel moment frame. TheDesigner must designate what inspections are required in accordancewith the local code, based on building occupancy, concrete strength,requirements of the local building official, and other considerations.

Because the Strong Frame ordinary moment frame includes pre-manufactured components, all welding inspections are completed duringthe manufacturing process. Welding of the frame members is performedon the premises of a fabricator registered and approved in accordancewith the requirements of IBC Section 1704.2.2 for fabricator approval,so special inspections contained in IBC Section 1704 are not required.Special inspection for seismic resistance required by IBC Section 1707for welding is completed during the manufacturing process.

If required, inspection of fastener assemblies (high-strength bolt, DTIwasher, hardened washer, and heavy hex nut) for the bolted beam-to-column connections is easy. Fastener assembly lots are randomlysampled and pre-installation verification testing is performed to confirminstallation procedures and performance of the fastener components.

The easy-to-use Direct-Tension-Indicator (DTI) washers included withevery Strong Frame moment frame installation kit make it easy toverify proper bolt pretensioning in the field – see page 15 for furtherinformation on use of the DTI washers. For projects where inspectionof the bolts is required, Certificates of Conformity for the fastenerassemblies may be obtained for each hardware kit lot number underLot Control for Structural Fastener Assemblies on the Strong FrameMoment Frame page at www.strongtie.com. The lot number is locatedon the beam and on the hardware box.

Frame Selection

Step 1Check if OMF ispermitted

Determine if an ordinary steel moment frame is permitted for your structure. For structures designed in accordance with ASCE 7-05Ordinary steel moment frames may be used in Seismic Design Categories A, B and C without limitations•Ordinary steel moment frames may be used in Seismic Design Categories D, E and F subject to limitations set forth in•Sections 12.2.5.6, 12.2.5.7, and 12.2.5.8

Step 2 Check R value If seismic loads are calculated using R > 3.5, convert loads by multiplying by the R used in design and dividing by 3.5.

Step 3Select nominalheight and width

Select the nominal height (8', 9', 10', 12', 14', 16', 18', or 19') for your structure where the frame will be installed and find thecorresponding allowable load table on pages 22–37. Next select the frame clear-opening width (8'-2", 10'-2", 12'-4", 14'-4", 16'-4", 18'-4", or 20'-4") that will accommodate the required wall penetration.

Step 4Check verticalloading

Compare vertical loads on your frame with the limits listed in footnotes 2 and 3 of the allowable load tables:If the beam is loaded with only uniformly distributed vertical loads and the allowable stress design (ASD) uniform loads•are all less than the limits listed in footnote 2, use “Maximum Shear” values. If S DS > 1.0, check if uniform dead load mustinclude additional vertical seismic load effects (see allowable load tables, footnote 2).If the beam is loaded with uniform vertical loads that exceed the limits, a single vertical point load at mid-span, or multiple•

point loads applied symmetrically about mid-span, use “Minimum Shear" values.If your vertical loading does not meet these criteria, use the Simpson Strong-Tie• ® Strong Frame™ Ordinary Moment FrameSelector software or contact Simpson Strong-Tie to perform a design for custom loading or complete alternate loadingworksheet on page 66.

Step 5SelectStrong Framemodel

Using the Maximum Shear or Minimum Shear as determined in Step 4, select a frame with a tabulated allowable ASD shear thatexceeds the applied load. For wind design, check that the tabulated drift meets drift limits established for the project. Drift may belinearly reduced if the applied load is less than the tabulated frame capacity. (See footnote 16 on allowable load tables.)

Step 6 Check WmaxFor frames selected using Minimum Shear values, check that the maximum total vertical load based on ASD load combinations isless than the tabulated value of Wmax. If not, select a different frame and re-check.

Step 7CheckStrong Framedimensions

Using nominal height and width tables above the allowable load tables, verify that the Strong Frame selected will accommodatethe required wall opening:

Check that the clear-opening width (W1) is equal to or greater than the wall opening width.•Check that the outside frame width (W2) fits within the available wall space.•Check that the frame's clear-opening height (H3) is equal to or greater than that required (remember to add the curb/ •stemwall height to H3 for installations with the frame base above the floor level).

Step 8Select bolttighteningrequirements

Determine if snug-tight or pretensioned bolts are required for the end plate connections:In Seismic Design Categories D, E, or F, pretensioned bolts are required•In Seismic Design Category A, B, or C, snug-tight bolts may be used when seismic design is based on R ≤ 3, otherwise•pretensioned bolts are required.

Step 9Select top platefasteners

In the allowable load tables, select between the nail (16d commons) and screw (1/4"x3-1/2" SDS) options for attaching a field-installed top plate to the frame nailers. For seismic design, quantity of fasteners must be increased if the connection is requiredto be designed as a collector for load combinations with overstrength (see ASCE 7-05, Section 12.10.2.1).

Tension Anchorage

Step 1Determineconcrete condition

Determine whether uncracked or cracked concrete is applicable for anchorage design (see ACI 318, Appendix D). Assumingcracked concrete is conservative.

Step 2Select anchoragedesign method

Determine which method to use for selecting anchorage solutions:Simplified – This is the quickest and easiest method, requiring only the column size and frame height to select the•anchorage. This method can result in a conservative design for some frames and loading conditions. The Simplified methodis not applicable for seismic designs that use R = 3.5.

Detailed – This method uses column reactions and anchorage assembly capacities to select a solution. The maximum•

column reactions tabulated in the allowable load tables may be used, or for further economy, the reactions calculated for theproject-specific design loads can be used (see footnotes 4 and 5 of the allowable load tables on pages 23–37).

Step 3Determine tensionreaction

Determine the maximum tension reaction for tension anchorage design:For Simplified anchorage design, no calculation of react ions is required. Solutions presented in Table 1.1 on page 39•consider maximum tension reaction for each group of frames.For Detailed anchorage design, use maximum tension reaction tabulated in the allowable load table for the frame selected, or•calculate tension reaction based on design loads in accordance with footnote 5 of the allowable load tables on pages 23–37.

Step 4Select minimumfooting size fortension

Determine minimum embedment and footing size for tension anchorage:For Simplified anchorage design, select embedment and footing width from Table 1.1 on page 39 based on column size and•nominal frame height.For Detailed anchorage design, use the Tension Anchorage Allowable Loads Table 1.2 on page 39 to select embedment and•footing width with a capacity that exceeds the tension reaction.

Step 5Determineanchorage

assembly strength

Standard strength anchorage assemblies are adequate for tension except where shown in the anchorage tables:For Simplified anchorage design, installations requiring high strength anchorage are determined as a part of shear•anchorage design (see footnote 8 of Table 1.1 on page 39)

For Detailed anchorage design, installations requiring high strength anchorage are designated in footnote 6 of Table 1.2•

on page 39.

Step 6Determine rodlength and footingsize

Add the step height (height of concrete above the top of footing) to the minimum required embedment, de, and select ananchorage assembly model number with an embedded rod length, le, that is equal or greater. If this value exceeds the maximumembedded rod length for the anchorage assembly, select an extension kit to achieve the necessary rod length. Note that theembedded rod length is different for OMFSL and OMFAB anchorage assemblies with the same total rod length. See Step 1 ofGeneral Shear Anchorage Design for selection of anchorage assembly type.

Shear-Anchorage Selection Procedure

General Shear Anchorage

Step 1Select anchorageassembly type

Select which anchorage assembly you want to use:The OMFSL anchorage assembly is easier to install and allows the frame to be installed flush with the edge of concrete, but•may require additional end distance.The OMFAB anchorage assembly offers higher shear capacities without increasing concrete strength or end distance, but•requires an increased edge distance and additional tie or hairpin reinforcement.

Step 2Select anchoragedesign method

Determine which method to use for selecting anchorage solutions:

Simplified – This is the quickest and easiest method, requiring only the column size and frame height to select the•anchorage. This method can result in a conservative design for some frames and loading conditions. The Simplified methodis not applicable for seismic designs that use R = 3.5.Detailed – This method uses column reactions and anchorage assembly capacities to select a solution. The maximum•column reactions tabulated in the allowable load tables may be used, or for further economy, the reactions calculated for theproject-specific design loads can be used (see footnotes 4 and 5 of the allowable load tables on pages 23–37).

Step 3Determine shearreactions

Determine the maximum shear reaction for shear anchorage design:For Simplified anchorage design, no calculation of reactions is required. Solutions presented in Table 2.1 (page 41) and•Table 3.1 (page 44) consider maximum shear reaction for each group of frames.For Detailed anchorage design, use maximum column shear reaction tabulated in the allowable load table for the frame•selected, or shear reaction calculated using footnote 4 of the allowable load tables on pages 23–37. For OMFSL, determine shearreaction at both tension and compression columns. For OMFAB, only the shear reaction at the compression column is required

OMFSL Shear Anchorage

Step 4

Determine inside

and outside enddistance

Determine the minimum inside and outside end distance in concrete:For Simplified anchorage design, determine directly from Table 2.1 on page 41.•

For Detailed anchorage design, use the shear reactions from Step 3 and the OMFSL shear capacities in Table 2.2 or 2.3.•Select an inside end distance with a capacity that exceeds the tension column shear reaction, and an outside end distancewith a capacity that exceeds the compression column shear reaction.

Step 5Determineanchorageassembly strength

If high strength anchorage is required for tension, specify a high strength OMFSL anchorage assembly. Otherwise, standardstrength anchorage assemblies are adequate for OMFSL except for shaded regions of the anchorage tables.

Step 6VerifyStrong Framedimensions

If additional studs are required for end distances, check that modified OMF dimensions will accommodate the required wall openingIf inside end distance exceeds that corresponding to the pre-installed nailer installed flush with inside end of curb, subtract•the thickness of additional studs required at each column from the clear-opening width, W1, and check that this still exceedthe required opening width.If outside end distance exceeds that corresponding to the pre-installed nailer installed flush with outside end of curb, add•the thickness of additional studs required at each column to the outside frame width, W2, and check that this still fits withinthe available wall space.

OMFAB Shear Anchorage

Step 4 Determinereinforcement

Determine the minimum concrete reinforcement required:

For Simplified anchorage design, determine directly from Table 3.1 on page 44.•For Detailed anchorage design, use the compression column shear reaction from Step 3 and the OMFAB shear capacities in•Table 3.2 on page 44 to select tie or hairpin reinforcement with a capacity that exceeds the shear reaction.

Step 5Determineanchorageassembly strength

If high strength anchorage is required for tension, specify a high strength OMFAB anchorage assembly. Otherwise, standardstrength anchorage assemblies are adequate for OMFAB except for shaded regions of the anchorage tables.
