Abstract

A reliability formulation is presented for thermally insulated load bearing plates subjected to the localized heat loading. The limit state function is defined in terms of stresses, which account for the additional in-plane compressive loads that the plate will sustain before collapse. The collapse strength of plates is determined with a non-linear finite element code that accounts for the elasto-plastic behavior and for the changes in material properties with temperature. A first order second moment approach is presented to quantify the uncertainty of the heat loads and to describe the importance of the governing variables in the limit state function. An example of the reliability analysis of a steel plate is provided using a time independent first order method.
