Design equations for plates subjected to heat loads and lateral pressure

摘要

A brief description is presented of the strength behaviour of rectangular plates subjected to fire-induced intense heat loads of such a magnitude as to degrade the mechanical properties of the material. Design curves are proposed to predict the collapse of the plates under the biaxial state of stress induced by heat loads. Interaction curves are also derived for the case of plates that are initially subjected to lateral pressures and later to intense heat loads.
