Question

The 10.5-k truck exerts the wheel reactions shown on the deck of a girder bridge. Assume the truck travels in either direction along the center of the deck, and therefore transfers half of the load shown in each of the two side girders. Assume the splice is a fixed connection and, like the girder, can support both shear and bending moment. Suppose that F1 = 7 k and F2 = 3.5 k . Follow the sign convention.

a) Determine the largest live shear the truck creates in the splice at C

b) Determine the largest bending moment the truck exerts in the splice.
