It also includes data worksheets for detailing bolts. The information includes: dimensions of bolts andnuts, washers, various bolt hole sizes, spacing of holes and back marks, bolt symbols, etc.
The Tensile Stress Areas are taken from BS 4190 for Ordinary Black Bolts, BS 3692 for PrecisionBolts and BS 4933 for Countersunk Bolts. The Tensile Stress Areas and Proof Loads for HSFG Boltsare taken from BS 4395: Part 1 for General Grade and BS 4395: Part 2 for Higher Grade (ParallelShank). Scope & method details of various worksheets are described below.
This worksheet calculates various capacities: Tensile, Single Shear, Double Shear and Bearing forvarious Ply thicknesses. The features are:

Shear Plane can be: Bolt Threads or Shank
When Shear Plane in the Shank is selected, a warning is displayed to remind that Threads should not bein the Shear Plane and that the use of many washers may be necessary to achieve it.
Bolt Holes can be Clearance, Over-size, Short-slotted, Long-slotted and Kidney-shaped
Bolt Diameters are: M1.6, M2, M2.5, M3, M4, M5, M6, M8, M10, M12, (M14), M16, (M18), M20,(M22), M24, (M27), M30, (M33), M36, (M39), M42, (M45), (M52), M56, (M60), M64 and (M68), thesizes in brackets being non-preferred.
Hole Edge Distance can be any user-typed value from 1.25 to 2.0 of the Bolt Hole DiameterD.
Connected Ply Grades can be: S275, S355 and S460
Connected Ply Thicknesses can be any User-Typed Values. They can be changed at the head row ofbearing values (shown in light green cell background) to suit any value required for design.
The Combined Tension and Shear Capacity can also be calculated for each bolt diameter. For anytyped value of Applied Tension F
t, the corresponding Shear Capacity F
sof Threads or Shank is
displayed in the adjacent cell.
Three Colours and Font styles are used to display Bearing Capacities. Values below the single shear
capacity are displayed in Red and Normal font. Values above the single shear and below the doubleshear capacity are displayed in Blue and Bold. Values above the double shear capacity are shown inGreen and Italic.

Design criteria for connections can be Non-slip in service and Non-slip under factored loads
Connected Ply Grades can be: S275, S355 and S460
Connected Ply Thicknesses can be any User-Typed Values. They can be changed at the head row ofbearing values (shown in light green cell background) to suit any value required for design.
The Combined Tension and Shear Capacity can also be calculated for each bolt diameter. For anytyped value of Applied Tension Ft, the corresponding Shear Capacity Fs of Threads or Shank isdisplayed in the adjacent cell.
To display bearing capacities 3 colours and font styles are used. The values below the single shear
capacity are shown in Red and Normal font. The values above the single shear and below the doubleshear capacity are shown in Blue and Bold. The values above the double shear capacity are shown inGreen and Italic.
Two worksheets give Fillet Weld Capacities for Steel Grades S275, S355 and S460, using E35, E42and E50 Electrodes.
One worksheet uses the Simple Method as per clause 6.8.7.2 and the other uses the DirectionalMethod as per Clause 6.8.7.3 of the code.
Gives Capacities for Full Penetration Butt Welds. The capacities calculated are Shear andTension/Compression strength for Steel Grades S275, S355 and S460using E35, E42 and E50electrodes respectively.

Fasten5950 is a Template for finding the Capacities of Bolts and Welds to BS5950-1: 2000. The boltscan be Ordinary, Countersunk or High Strength Friction Grip Bolts. Welds can be Fillet or FullPenetration Butt Welds.
To load Fasten5950 on to your computer, copy this file into Microsoft Office folder for its Templates.Generally the path to this folder in Excel 97 is:
If you receive an Excel Warning about running Macros and are prompted for whether to load them,answer YES to Load and Enable Macros. Fasten5950 incorporates VB Macros and to allow yourcomputer to use them is vital for its operation.
Fasten5950 is used as a desktop reference. A designer can have it running as an Excel file and refer toit for finding capacities and detailing information for bolts and welds as and when required.
When use of a desktop computer is not available, Fasten5950 can also be used to print tables of bolt andweld capacities on paper. When used in this way, for example, a total of 216 tables can be produced forNon-preloaded bolts and 384 tables for the preloaded HSFG bolts.
When Fasten5950 is loaded, a HOME page is displayed on the screen for links to its variousworksheets. It selects a set of initial default values to ensure a standard start for minimizing usageerrors.
The initial default options for Non-preloaded bolts are: Hexagon Head Bolts, Shear Plane in Threads,Bolt Grade 8.8, Connected Ply Grade: S275(43), Clearance Bolt Holes.
The initial default options for HSFG Bolts are: Hexagon Head Bolts, General Grade, 0.5 Slip Factor,Non-slip under factored loads design criteria, Clearance Holes and Connected Ply Grade S275 (43).

The shear capacity Psis calculated as:
Ps= p
sA
s
psis the shear strength of bolts taken from Table 30 of the code, and
As
is the Tensile Stress Area of the bolts as specified in respective British Standards.
The bearing capacity is taken as lesser of the bolt bearing capacity Pbb
and the connected ply bearing
capacity Pbs
. The bolt bearing capacity Pbb
is calculated as:
Pbb
= d tp
pbb
d is the nominal bolt diameter,
tp
is the thickness of the connected ply.
pbb
is bearing strength of the bolt obtained from Table 31 of the code.
Whenthe bolts are countersunk, tp
is taken as the ply thickness minus half the depth of countersinking.
The depth of countersinking is taken as half the bolt diameter based on a 90o countersink.
When the Edge Distance e of a bolt hole in the direction of its bearing load is not less than 2d, thebearing capacity of the connected ply Pbs
is calculated as:
Pbs
= kbs
d tp
pbs
kbs
is a coefficient to allow for hole type and taken as:
- for bolts in standard clearance holes kbs
= 1
- for bolts in oversize & short slotted holes kbs
= 0.7
- for bolts in long slotted and kidney-shaped holes kbs
= 0.5
pbs
is the bearing strength of the connected parts obtained from Table 32.
When the end distance e of the bolt hole in a ply is less than 2d, the bearing capacity of the connected
ply Pbs is calculated as:P
bs= 0.5 k
bse t

bs
e is the end distance of the bolt hole.
The tension capacity Ptof a bolt is calculated as:
Pnom = 0.8 ptA
t as nominal capacity by Simple Method to Clause 6.3.4.2
Pt
= ptA
t as tension capacity by Exact Method to Clause 6.3.4.3
