Computational Limit Analysis is a numerical tool that allows the user to rapidly and directly determine the ultimate limit state for a general problem geometry without the need to iterate or timestep to a solution. This paper summarises recent work placing Computational Limit Analysis within a rigorous theoretical framework that can be used in the context of modern limit state design codes such as Eurocode 7. It then illustrates how a Computational Limit Analysis approach may be carried out for a range of example foundation and retaining wall problems within the Eurocode 7 context.

A particular focus of the paper is to examine the key issue of action/resistance factoring as used in Eurocode 7 Design Approach 1 Combination 1 and Design Approach 2.
