• The plan of a mat foundation with column loads is shown in
Figure 2. Use the rigid method to calculate the soil
pressures at point A, B, C, D, E, F, G, H, , J, K, L, M and N. The
size of the mat is 76 ft x 96 ft, all columns are 24 in x 24 in
in section, and qlnet = 1.5 kip/ft². Verify that the soil
pressures are less than the net allowable bearing capacity.
