A 500 mm wall supports a dead load of 800 KN/m and live load of 780 KN/m and a horizontal dead load of 15 KN/m and horizontal live load of 20 KN/m subjected to a distance 0.50 m from the center of the footing. The allowable soil bearing pressure is 300 KPa. The base of the footing is 2 m below the grade. Assume concrete weighs 23.5 KN/m3 and that the soil has a specific gravity of 2.60, porosity of 0.60 and degree of saturation is 60%. Above the natural ground surface lies a tank half full of oil with specific gravity f 0.80 and the tank is 5 m high (oriented as vertical right cylinder). The total depth of footing is 600 mm with a steel covering of 100 mm. Use fc=21 MPa and fy = 275 MPa. Determine: a. dimension of wall footing rounded to the nearest 0.10 m. b. Adequacy in beam shear c. Steel reinforcement area required
