Question about concrete foundation ( Pressure Engineering) PLEASE HELP?
A load of 12 tonnes is applied through a steel column onto a reinforced square concrete pad foundation. If the bearing capacity of the soil is 120KN/M2 and a factor of safety of 3 is to be applied,
Foundation area required is therefore
LOAD = 12TONNES = 12X 9.8067 KN.
ALLOWABLE BEARING STRESS = 12O/3 = 40 KN/MSQ.
FOUNDATION AREA = 12X 9.8067/40 = 2.942SQ.M
But, if the same load was applied over each metre run of a wall to be supported on a strip foundation, what minimum width of foundation would then be required, assuming the same bearing capacity and factor of safety were applied??????.

Your math is far beyond what I under stand but there is something special about concrete . All loads should be compression not to stretch or flex the concrete. That is why the Romans built arch supports for there aqua-duck support. the load is all compression.
