Solution to Problem 128 Bearing Stress

Problem 128
128-beam-girder-connection.gifA W18 × 86 beam is riveted to a W24 × 117 girder by a connection similar to that in Fig. 1-13. The diameter of the rivets is 7/8 in., and the angles are each L4 × 3-1/2 × 3/8 in.. For each rivet, assume that the allowable stresses are τ = 15 ksi and σb = 32 ksi. Find the allowable load on the connection.
 

Summary of the problem
Given:
Shape of beam = W18 × 86
Shape of girder = W24 × 117
Shape of angles = L4 × 3-1/2 × 3/8
Diameter of rivets = 7/8 inch
Allowable shear stress = 15 ksi
Allowable bearing stress = 32 ksi
 

Required:
Allowable load on the connection
