Calculate the strength of an ISA100 x 75 x 8mm used as a tie member with longer leg connected at ends by 16mm diameter rivets. Provide tensile stress as 150N/ mm2

Given data:

ISA 100×75×8mm, diameter of rivet = 16mm, tensile strength = 150N/mm²

At = 26.72 cm² = 2672mm² (from steel table)

Strength = Stress × At × Anet

Anet = A1+ (A2 × K)

K = (3A1)/3A1+A2

A1 = t(b- t/2) = 568mm²

A2 = (l-d-t/2) = 100-17.5-8/2 =78.5mm²

{where d= nominal diameter+ 1.5}

Therefore, K = (3× 568) /3(568)+ 78.5 = 0.95

Anet = 568 +(78.5×0.95) = 642.575mm²

Now, the strength = 150 × 2672 ×642.575 = 257.54KN
