Abstract

A statically admissible stress field was constructed by using nonlinear optimization sequential quadratic programming (SQP) algorithm and FEM. Based on the rigid plastic assumption for soil materials, adopting lower bound theorem, the bearing capacity of rectangular surface footing was calculated. The example indicates that the application of SQP algorithm is successful.

Key words： soil mechanics; limit analysis method; lower bound theorem; non-linear programming; bearing capacity of footing; sequential quadratic programming algorithm
