Centres of two columns A and B are 3 m apart. Column A is supported by a footing 1.2 × 1.2 m and column B by a footing 1 x 1 m. Column A is founded at a depth of 2.5 m below ground level and column B at 1.5 m. The contact pressure on the soil under each footing is 425 kPa. Find the increase in vertical stress at a depth of 9 m vertically below the centres of A and B and the point midway between them. Use the Newmark method. B 3m 1.5m 2.5m 1 m 9m 1.2 m Scheme 2.29
