Design a rectangular combined footing to support two columns. Column A is 300×300mm which carries a dead and live load of 550kN and 500kN respectively. The column B has a section of 400×400 mm & carries dead and live load of 700kN and 570kN respectively. The centre to centre spacing is 3m. the allowable soil pressure is 200kN/m2. Use M20 grade concrete and Fe415 grade steel. Later, while checking you discovered that the live load to be carried by Column B is only 300 kN. Provide your modification and suggestion to your earlier design.
