A retaining wall shown has a thickness of t=500mm. Use f'c=21 MPa and fy=280 MPa for diameter 20mm vertical bars. The ultimate soil bearing capacity is 500 kPa. Use a clear cover of 50mm in designing the wall. Calculate the following: 1. Total Active Force per unit length acting on the wall. 2. Total Passive Force per unit length acting on the wall. 3. The Active Moment per unit length acting on the base of the wall.
