A truck exerts wheel reactions P1 = 10 kips and P2 = 4 kips on the deck of a bridge. Determine the maximum positive moment at C. Assume the truck only travels in the direction shown. The influence lines for VC and MC are shown, along with the peak values of the influence lines.

Determine the reaction moment at A. Let P = 140 lb, a = 55 in., and EI = 46 × 106 lb·in.2.

Determine the slope at A that would be caused by the concentrated force if the fixed support was a pin support, instead. Let P = 208 lb, a = 61 in., and EI = 37 × 106 lb·in.2.

Determine the magnitude of the bending moment at A. Let w = 2.8 kip/ft, L1 = 20 ft, and L2 = 33 ft. Assume EI = constant.

Determine the fixed end moment FEMBA. Let P = 17 kips, L1 = 24 ft, and L2 = 12 ft. Assume EI = constant.

Determine the fixed end moment FEMBA with a settlement of 1.1 in. at support B.   As in Chapter 16, include the effect of settlement in the FEM calculation.  Let w = 3.0 kip/ft, L = 20 ft, E = 29,000 ksi and I = 1,550 in.4.

The FEM for a section that has no external load is equal to zero.

Determine the slope at A that would be caused by the concentrated force if the fixed support was a pin support, instead. Let P = 198 lb, a = 51 in., and EI = 124 × 106 lb·in.2.

Determine the horizontal distance from column ADG to the centroid of the columns. Assume all of the columns have the same cross sectional area. Let P1 = 20 kN, P2 = 48 kN, L1 = 8.2 m, L2 = 6.2 m, and L3 = 6.1 m.

Determine the deflection at B that would be caused by the distributed load if the middle support was not there. Let w = 9 lb/in., a = 55 in., and EI = 129 × 106 lb·in.2.
