This paper uses theorem of shakedown to assess the shakedown limit of elastic-plastic offshore structures. For this aim, an envelope of elastic response of the structure to cyclic loading cases is required. The shakedown limit is basically a valid collapse mechanism and can be quantified using yield

The quasistatical shakedown behaviour of elastic-plastic bodies is investigated under the assumption of small strains but finite displacements. A condition guaranteeing shakedown is obtained. Two methods for the treatment of particular problems are presented and one of them is illustrated by the exa
## a b s t r a c t We propose a numerical method for the computation of shakedown loads of engineering structures subjected to varying thermo-mechanical loading. The method is based on Melan's lower bound shakedown theorem using the von Mises yield criterion. The resulting nonlinear convex optimiza
