The paper faces the problem of the evaluation of the residual strength of simple reinforced concrete schemes after fire. At this aim an analytical model, already developed by the authors, is extended and upgraded in order to account for the damages induced by the fire actions. A conventional temperature-fire curve is considered and proper constitutive relationships for the materials after cooling are chosen, according to experimental data available in literature and to European code suggestions. The residual bending moment-mean curvature relationships of cracked elements are obtained and implemented for the analysis of beams.

A conventional temperature-fire curve is considered and proper constitutive relationships for the materials after cooling are chosen, according to experimental data available in literature and to European code suggestions.
