1. To reinforce an Ibeam, W250 X 44.8, two plates, 12 X 175 mm, have been bolted to the Ibeam using 18-mm diameter bolts spaced longitudinally every 125 mm. The allowable shear stress in the bolt material is 85 MPa. Determine the largest allowable shear force, V, that can be applied to the reinforce beam. Properties of the W250 X 44.8 are as follows: Iz = 71.1)(106 mm4, depth (i.e., height) = 266 mm. Ans: Vmax = 180.6 kN W W250 X 44.8
