Steel Structure Design - Engineering

Q1:

In a truss girder of a bridge, a diagonal consists of mild steel flat 4001.S.F. and carries a pull of 80 tonnes. If the grossdiameter of the rivet is 26 mm, the number of rivets required in the splice, is

A 6

B 7

C 8

D 9

E 12

ANS:C - 8

The load carried by splice = total load÷2.
Rivet value = 0.785*26*26*90 = 47.78KN,
Number of rivet = 400÷47.78 = 8.37.
= 9 rivets.
