SITUATION 3: A 12-m simply supported bridge is constructed with 100-mm concrete slab deck supported by precast concrete stringers spaced 800 mm on center. Analyze the stringers when subjected to a moving load consisting of 3 evenly spaced axle loads at 3 m and equivalent to 20 kN, 30 kN and 40 kN respectively. The self-weight of the stringers is 8.5 kN/m and the concrete deck has a unit weight of 24 kN/m³. Neglect all other superimposed loads. Calculate: (a) the maximum shear force in the stringers; (b) the maximum bending moment in the stringers.

1. Compute the design and allowable compressive strength of a 12 meter built-up column composed of a steel plate with an attached channel section on each side. The web of both channel bars are welded to the steel plate, with their local x-axes coinciding with that of the steel plate. The thickness of the plate is 6 mm, with its width equal to the depth of the larger channel section. Assume that the column has fixed ends and is supported about the weaker at middle thirds, and about the stronger axis at mid-height. Assume all steel used are A36 steel.
