Stresses from Loads over Rectangular Areas
Publication: Journal of Geotechnical Engineering
Volume 112, Issue 10
Abstract
The fundamental solution for the stresses induced in a semi-infinite isotropic homogeneous elastic medium by a concentrated point load applied normally to its plane surface is extended to an optimally designed rectangular footing subjected to biaxial bending with one corner having zero contact pressure. Formulas are presented to determine the vertical stress beneath the zero loaded corner and the diagonally opposite corner having maximum soil pressure. A design example is given to illustrate the use of equations.
