Topic:Bolted Steel Connection - Civil Engineering
*Use latest NSCP/NSCP 2015 formula to solve this problem
The butt connection shows 8-22 mm dia. A325 bolts spaced as follows:
S1 = 40 mm S3 = 50 mm t1 = 16 mm
S2 = 80 mm S4 = 100 mm t2 = 12 mm
Steel strength and stresses are:
Fy = 248 MPa Fu = 400 MPa
Allowable tensile stress on the gross area = 148 MPa
Allowable tensile stress on the net area = 200 MPa
Allowable shear stress on the net area = 120 MPa
Allowable bolt shear stress, Fv = 120 MPa
Bolt Hole diameter = 25 mm
Questions:
Calculate the allowable tensile load T, under the following conditions.
a) Based on the gross area of the plate
b) Based on the net area of the plate
c) Based on block shear strength
