Extracted text: The floor system of a gymnasium consists of a 130- mm-thick concrete slab resting on four steel beams (A = 9;100 mm") that, in turn, are supported by two steel girders (A = 25;600 mm2), as shown in Fig. P2.7. Determine the dead loads acting on beam BF and girder AD. Steel floor beam (A = 9,100 mm²) Steel girder (A = 25,600 mm²) D-Steel T column A B C I- 130 mm 10 m concrete slab F 3 at 5 m= 15 m G AG.
