Multiple choice

A truss tie consisting of 2 ISA 75 x 75 x 8 mm carries a pull of 150 kN. At ends the two angles are connected, one each on either side of a 10 mm thick gusset plate, by 18 mm diameter rivets arranged in one row. The allowable stresses in rivet are fs = 90.0 N/mm2 and fbr = 250 N/mm2.

Minimum number of rivets required at each end is

  1. 2

  2. 3

  3. 4

  4. 5

C Correct answer
Explanation

The number of rivets is determined by dividing the total load by the lesser of the rivet's shear capacity or bearing capacity. With 150 kN total load and two angles, each rivet carries a portion of the load. Calculating capacities leads to 4 rivets.
