The floor system of a gymnasium consists of a 130-mm-thick concrete slab resting on four steel beams (A = 8,800 mm2) that, in turn, are supported by two steel girders (A = 25,100 mm2). Determine the point load acting on girder AD at point C caused by dead load.

The floor system of a gymnasium consists of a 120-mm-thick concrete slab resting on four steel beams (A = 9,500 mm2) that, in turn, are supported by two steel girders (A = 26,200 mm2). Determine the point load acting on girder AD at point B caused by dead load.

Use Robot to determine the magnitude of the vertical reaction force at A. Let w = 30 kN/m, and L = 8 m. Delete the self-weight of the beam.

Determine the magnitude of the reaction moment at A. Let P1 = 42.3 kips, P2 = 32.9 kips, and a = b = c = d = 11 ft.

Determine the magnitude of the approximate bending moment at D in girder DE. Let w1 = 28 kN/m, w2 = 36 kN/m, L1 = 8 m, L2 = 7 m, and L3 = 6 m.

The floor of an apartment building is subjected to a uniformly distributed load of 38.7 psf over its surface area. Determine the axial load acting on column C.

Hydrostatic pressure acts in what direction?

The beam supports a single live load of 2,350 lb, a uniform live load of 400 lb/ft, a uniform dead load of 160 lb/ft. Determine the maximum positive shear that can be developed at point B. Assume the support at A is a pin and C is a roller. The influence lines for VB and MB are shown, along with the peak values of the influence lines.

Choose the equation that will give the largest factored load when D = 36 kip, L = 2 kip, Lr = 12 kip, and S = 20 kip.
