,1–1. The floor of a heavy storage warehouse building is
made of 6-in.-thick stone concrete. If the floor is a slab
having a length of 15 ft and width of 10 ft, determine the
resultant force caused by the dead load and the live load.
From Table 1–3
DL = [12 lb/ft2 # in.(6 in.)] (15 ft)(10 ft) = 10,800 lb
From Table 1–4
LL = (250 lb/ft2)(15 ft)(10 ft) = 37,500 lb
