5. The floor system of a gymnasium consists of a 130- mm-thick concrete slab resting on four steel beams (A=9100 mm) that, in turn, are supported by two steel girders (A= 25600 mm³), as shown in Fig. P2.7. Determine the dead loads acting on beam BF and girder AD. Use Table 2.1 for the unit weight of materials.
