Solution 1.6-1 Angle bracket bolted to a column SECTION 1.6 Shear Stress and Strain 25 Shear Stress and Strain Problem 1.6-1 An angle bracket having thickness t 5 0.5 in. is attached to the flange of a column by two 5 / 8 -inch diameter bolts (see figure). A uniformly distributed load acts on the top face of the bracket with a pressure p 5 300 psi. The top face of the bracket has length L 5 6 in. and width b 5 2.5 in. Determine the average bearing pressure s b between the angle bracket and the bolts and the average shear stress t aver in the bolts. (Disregard friction between the bracket and the column.) t L p b Two bolts d 5 0.625 in. t 5 thickness of angle 5
