A two-way reinforced concrete building floor system is composed of slab panels measuring
6\times 7.5min plan, supported by shallow column-line beams cast monolithically with the slab as shown. The slab is assumed to have a thickness of
180mm. The beam dimensions
350\times 500mmwill be assumed. Design the exterior panel to carry a live load of
7k(N)/(m^(2))in addition to the self-weight of the floor. Use
