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

1–2. The floor of the office building is made of 4-in.-thick
lightweight concrete. If the office floor is a slab having a
length of 20 ft and width of 15 ft, determine the resultant
force caused by the dead load and the live load.
From table 1–3
Dl = [8 lb/ft2 . In. (4 in.)] (20 ft)(15 ft) = 9600 lb from
table 1–4
