Abstract
Bearing capacity of rectangular footings was simulated with three-dimensional finite difference program. In the analysis, soil is modeled using Mohr-Coulomb model. Shape effects on bearing capacity of rectangular footing are evaluated without using the conventional superposition. To avoid error induced by superposition, cohesion and soil unit weight are normalized as one parameter. Numerical results show that bearing capacity of rectangular footing decreased with the increase of footing aspect ratio. The effects of footing shape are also different with the characteristics of soil. In general, effects of footing shape are more obvious for soils with high cohesion, while they are slight on soils with low cohesion.
