A 200 mm wide concrete block wall carries a factored vertical design load of 172 kN/m. The
sustained load for settlement is 130 kN/m. It is to be supported on a continuous footing made
of 18 MPa concrete and 280 MPa steel. The soil has an allowable bearing pressure for bearing
capacity of 180 kPa (using LRFD methods) and an allowable bearing pressure for settlement of
110 kPa. The groundwater table is at a great depth. The local building code requires that the bot-
tom of this footing be at least 500 mm below the ground surface. Determine the required footing,
width, thickness, and design the lateral and longitudinal steel. Show your design in a sketch.
