Question: A reinforced concrete column of 18"x18" size supports a service dead load of 120 kips and a service live load of 90 kips. The loads are acting at the base of the column. The allowable bearing capacity, qa, is 6000 psf at the level of the base of the footing, which is 4 ft below the finish floor level as shown in Fig. 03. Take fe' = 3 ksi and fy = 60 ksi. It is required to; (a) Analyze the footing. Take unit weight of soil equal to 120 pef) (b) Design the footing for flexure using #6 bar only. 18"x18" RC column FFL 4'-0" h= 21" Figure 03.
