Description
Summary:A procedure for strength reduction analysis using finite-element limit analysis is presented. The scheme is completely general and does not require decision making regarding the loads needed to drive the system to failure. Rather, the scheme is based on the ability of modern interior-point methods to detect infeasibility in a controlled and reliable manner. The new scheme is illustrated by an example involving a strip footing on top of a slope.
