The floor system of an apartment building consists of a 4-in.-thick reinforced concrete slab resting on three steel floor beams, which in turn are supported by two steel girders, as shown in the figure. The areas of cross section of the floor beams and the girders are 18.3 in² and 32.7 in², respectively. The aspect ratio (beam length to spacing ratio) of the slabs in the framing plan is 25 ft/12 ft = 2.1. 1. Determine the dead loads acting on the beam CD and the girder AE.

A composite beam is fabricated by bolting two 3.6-in.-wide by 13-in.-deep timber planks to the sides of a 0.5-in. by 13-in. steel plate. The moduli of elasticity of the timber and the steel are 1700 ksi and 29000 ksi, respectively. The simply supported beam spans a distance of 25 ft and carries two concentrated loads P, which are applied as shown. Assume LAB = LCD = 7 ft, LBc = 11 ft, b = 3.6 in., d = 13 in. and t = 0.5 in. (a) Determine the maximum bending stresses o,,o, produced in the timber planks and the steel plate if P = 3.7 kips. (b) Assume that the allowable bending stresses of the timber and the steel are 1010 psi and 26800 psi, respectively. Determine the largest acceptable magnitude for concentrated loads P. (You may neglect the weight of the beam in your calculations.) Answers: LAB (a) o, = (b) P = i i B LBC b F لالها b Cross section C kips. d ksi, o, = LCD D ksi.
