A wall footing supports a 314 mm thick reinforced concrete wall with a dead load 312.37 kN/m and a live load 234.18 kN/m. The weight of the footing and soil is assumed to be 16.17% of the dead load. The soil bearing capacity of the soil is 159 kPa. Concrete strength f'c = 24.8 MPa and fy = 276 MPa. Use the thickness of footing = 482 mm and the centroid of the main bars is 80 mm from the bottom of the footing. Solve the required area of tension reinforcement per meter length (mm2/m) of the wall footing. Note: Use the exact value for the width (B). Do not rqund off.
