The two columns (A and B) of a framed structure are 3 m centers apart. Column A is supported on a square pad 1.25mx1.25m. The base of which is 2.5 m below GSL. The footing of column B is Imx Im and its base is at 1.5 m below GSL. The contact pressure under each column is 500 kPa. Consider the bases as point loads to find the increase in stress at a depth 5 m below GSL: (0) vertitally below the columns centers (ii) at a point midway between the two columns. If the coefficient of compressibility of the soil is m,- 3x10-3 m2/kN, compute the differential settlement between the columns, assume the thickness of the compressible soil to be 5 m below column A and 7 m below column B.
