Department of Civil Engineering Boussinesq Solution for Stresses Beneath the Corner of a Rectangular Loaded Area The attached chart is used to calculate the increase in stress beneath the corner of a rectangular loaded area. The increase in vertical stress, .£lO v , at a depth, z, is expressed as, where q is the stress intensity at the ground surface and I3 is an influence coefficient. Values OfI3 are given on the attached chart. The values depend on the two dimensionless quantities, m and n, which are defined as follows:
