Allowable Stress Design

Design values for use with allowable stress design (working stress design) shall be established as follows: Rallow,ASD = Rdα

where Rd = � Rk represents the limiting design strength in tension (� Nn ) or shear ( � Vn ) as calculated according to ACI 318 D.4.1.1 and D.4.1.2

Table 5 — The value of αα shall be taken as follows:

Reference for strength αreduction factors including seismic excluding seismicACI 318 D.4.4 1.1 1.4ACI 318 D.4.5 1.2 1.55

1 Values are for single anchors with no edge distance or spacing reduction. For other cases, calculation of Rd as per ACI 318-05 and conversion to ASD in accordance with Table 5.

2 Values are for normal weight concrete. For sand-lightweight concrete, multiply values by 0.85. For all-lightweight concrete, multiply values by 0.75. See ACI 318-05 D.3.4.

3 Condition B applies where supplementary reinforcement in conformance with ACI 318-05 D.4.4 is not provided, or where pullout or pryout strength governs. For cases where thepresence of supplementary reinforcement can be verified, the strength reduction factors associated with Condition A may be used.

4 Allowable static tension loads for 2,500 psi are calculated by multiplying the concrete breakout strength Nb by the strength reduction φ factor of 0.65 and dividing by an α of 1.4according to ICC ESR-1917 Section 4.2. Nb is calculated as per ACI 318-05 D.5.2.2. This load may be adjusted for other concrete strengths according to ICC ESR-1917 Section4.1.3 by using the following equation.

Nb,f'c = Nbf 'c

4 Allowable static tension loads for 2,500 psi are calculated by multiplying the pullout strength Npn by the strength reduction φ factor of 0.65 and dividing by an α of 1.4 according toICC ESR-1917 Section 4.2.

4 Allowable seismic tension and shear loads are calculated by multiplying Npn,deck and V sa,deck by the strength reduction φ factor of 0.65, the seismic reduction φ factor of0.75 according to ACI 318 D3.3.3, and then divided by an α of 1.1 according to ICC ESR-1917 Section 4.2.

5 Allowable non-seismic tension and shear loads are calculated by multiplying Npn,deck and V sa,deck by the strength reduction φ factor of 0.65 and dividing by an α of 1.4according to ICC ESR-1917 Section 4.2.

1.Hammer drill a hole to the same nominal diameter as the Kwik Bolt TZ. The hole depthmust exceed the anchor embedment by at least1/4 inch. The fixture may be used as a drillingtemplate to ensure proper anchor location.

2.Clean hole.

3.Drive the Kwik Bolt TZ into the hole usinga hammer. The anchor must be drivenuntil at least 4 threads are below the surface of the fixture.

4. Tighten the nut to the recommendedinstallation torque.

The Kwik Bolt 3 (KB3) is a torquecontrolled expansion anchor, whichprovides consistent performance for awide range of mechanical anchorapplications. This anchor series isavailable in carbon steel with zincelectroplated coating, carbon steel withhot-dip galvanized coating, 304stainless steel and 316 stainless steelversions.The threaded stud version ofthe anchor is available in a variety ofdiameters ranging from 1/4 in. to 1 in.depending on the steel and coatingtype. Applicable base materials includenormal-weight concrete, structurallightweight concrete, lightweightconcrete over metal deck, and groutfilled concrete masonry.

Guide Specifications

Torque controlled expansion anchorsshall be Kwik Bolt 3 supplied by Hiltimeeting the description in FederalSpecification A-A 1923A, Type 4. Theanchor bears a length identificationmark embossed into the impact section(dog point) of the anchor identifying theanchor as a Hilti Kwik Bolt 3 in theinstalled condition. Anchors aremanufactured to meet one of thefollowing conditions:

1. The carbon steel anchor body, nut and washer have an electro-plated zinc coating conforming to ASTM B633 to a minimum thickness of 5 µm.

2. The carbon steel hot-dip galva-nized anchor body, nut, and washer conform to ASTM A153.The stainless steel expansion elements conform to either AISI 304 or AISI 316.

3. The stainless steel anchor body,nut, and washer conform to AISI304. The stainless steel expansionelements conform to either AISI 304 or AISI 316.

4. The stainless steel anchor body,nut, and washer conform to AISI316. The stainless steel expansionelements conform to AISI 316.

Product Features

• Length identification code facili-tates quality control and inspectionafter installation.

• Through fixture installation andvariable thread lengths improveproductivity and accommodate various base plate thicknesses.

• Raised impact section (Dog Point)prevents thread damage duringinstallation.

• Anchor size is same as drill bit sizefor easy installation. For temporaryapplications anchors may be driveninto drilled holes after usage.

• Mechanical expansion allowsimmediate load application.

Installation

Drill hole in concrete, structurallightweight concrete, or grout filledconcrete masonry using a Hilti carbidetipped drill bit and a Hilti rotary hammerdrill. Remove dust from the hole with oilfree compressed air or vacuum.Alternately for 1/2, 5/8, 3/4, and 1 inchdiameter Kwik Bolt 3 anchors, the holemay be drilled using a matchedtolerance Hilti DD-C wet diamond corebit for anchoring applications. The slurrymust be flushed from the diamondcored hole prior to anchor installation.The minimum hole depth must exceedthe anchor embedment prior to torquingby one hole, diameter. Drive the anchorinto the hole using a hammer. Aminimum of six threads must be belowthe surface of the fixture. Tighten the nutto the recommended installation torque.
