WebFor shear tabs that meet this criteria, the bolt group eccentricity coefficient can be ignored (per page 10-102 of manual): Standard configuration; Standard holes for up to 9 bolts; For standard holes with n = 10 to 12, use e = n-4 and 1.25 factor on C. Short-slotted holes for up to 12 bolts; AISC 14th Edition (360-10) Double Angle Connections WebDec 7, 2024 · The equation is shown below. R = R u l t ( 1 − e − 10 Δ) 0.55. Since the bolt group capacity adapted the AISC method, the provisions in determining the design bolt eccentricity of the bolt group also follows Table 10-9 of the AISC 15th Ed. This is applicable on SkyCiv’s AS Web Side Plate connection. For Single Angle connections, both the ...
WebThe relation between applied torque and axial force - or load - in a bolt can be calculated in this general equation as. T = K F d (1 - l/100) (1) where. T = wrench torque (Nm, lbf ft) K = constant that depends on the bolt material and size. d = nominal bolt diameter (m, ft) WebJan 19, 2024 · It involves calculating the bolt group coefficient and requires an intensive iteration since its mathematical formulation is not a closed-form solution. To make the process easier, the American Institute of Steel Construction, in its AISC Manual, provided lookup tables to determine the bolt group coefficients through interpolation.
