1. A square footing 1.6m x 1.6m having a thickness of 500 mm supports an interior 400 mmx400 mm square column is constructed by using f = 20.7 MPa normal-weight concrete and Grade-276 bars (fy = 276 MPa). The footing has 8-20mmo reinforcements, both ways and is terminated in 180° standard hook so that reinforcement may be assumed to be fully developed at the critical sections. The top of the footing will be covered with 500-mm of fill and 100-mm concrete thick basement floor. The basement floor loading is 2.4 kPa. Soil parameters: All = = 18 kN/m³, Ysoil = 16.5 kN/m³, = 30°, c = 0 kPa, Df = 2.0m. Use FS = 2.0 and assume general shear failure, determine the maximum service axial load (Pmax,service = PD + PL) that the footing can carry if PLIVE = 3PDEAD.
