Description of the problem
To verify the vertical stress at any point A below a rectangular loaded area, the stress on soil obtained by Das (1983) (Example 6.3, page 370) using influence coefficients of Newmark (1935) are compared with that obtained by ELPLA.
A distributed load of q = 50 [kN/m2] acts on a flexible rectangular area 6 [m] × 3 [m] as shown in Figure 1. It is required to determine the vertical stress at a point A, which is located at a depth of z = 3 [m] below the ground surface.
