Square footing over sandy soil with qall = 224.7 kPa and soil unit weight
is of 18 kN/m3 carrying square
column (0.4x0.4) m2 with dead load
=1800 kN and live load 1200 kN. The
unit weight of the used reinforced
concreate footing is 24 kN/m3and fc
=21 mPa. The depth of embedment
is Df 1.8 m. Assume the height of
foot (h = 0.8 m and the concrete
cover = 0.1 m). Assume (1.4
DL+1.7LL=qu). The bending moment
is equal to
