Figure 1 shows a portion of the third floor office plan of the federal building in downtown Denver.
The beams and girders are simply supported and support a 4 in. thick concrete floor slab. Assume the self-weight of the beams and girders is 68 lb/ft. Find the maximum bending moments at ultimate conditions in beam B1 and girder G1.
Consider moveable partition as part of dead loads.
Hint: i) girder G1 supports beams B1 and B2 only; ii) dead loads consist of slab, partition, and beam/girder.
