The corner panel of a typical floor of a warehouse is shown in Figure P5.55. It consists of a 10-in.thick reinforced concrete slab supported on steel beams. The slab weighs 125 lb/ft 2 . The weight of light fixtures and utilities suspended from the bottom of the slab is estimated to be 5 lb/ft 2 . The exterior beams B 1 and B 2 support a 14-ft-high masonry wall constructed of lightweight, hollow concrete block that weighs 38 lb/ft 2 . We assume that the tributary area for each beam is shown by the dashed lines in the Figure P5.55, and the weight of the beams and their fireproofing is estimated to be 80 lb/ft. Draw the shear and moment curves produced by the total dead load for beams B 1 and B 2
