Summary

A strategy for efficient treatment of load combinations is proposed with the aim of making the shakedown analysis an affordable design tool for practical applications. This paper considers three-dimesional frames subjected to complex combinations of statical and dynamical loads defined according to Eurocode rules. The yield surface of the sections is defined by its support function values associated with presso-flexural mechanisms and it is approximated as a Minkowski sum of ellipsoids. An algorithm capable of detecting the significant vertexes of the elastic envelope and usable in the case of response spectrum analyses, is proposed.
