Averay 80 Homework: 300 300 200 1100 1200 1800 1800 1800 1200 The clear width of a highway bridge deck is 6.0m, and the vehicle load class is Highway - II. The standard calculated span is 20 m, the diaphragm spacing is 4.0 m. The girder consists of 4 T-shaped beams with the 1.8 m center distance of the beams. The average thickness of the bridge deck is 8 cm with the unit weight 24 kN/m. The average flange thickness of T-beam is 160 mm with the unit weight 25 kN/m. The web width is 200 mm, with a 1500 mm in height. (Impact coefficient u=0.3) Requirement: calculate the bending moment of the bridge deck under the back wheel.
