Textbook Problem

The roof system of an office building consists of a 4 in. thick reinforced concrete slab resting on four steel beams (A = 16.2 in.²), which are supported by two steel girders (A = 42.9 in²). The girders, in turn, are supported by four columns, as shown in Fig. P2.8. Determine the dead loads acting on the girder AG.
