Layered section analysis of RC slabs subjected to fire

Abstract

In this paper, an attempt has been made to extend application of the Flexural model to stress and strain analysis of flexural reinforced concrete members subjected to high temperature. Constitutive models and key material parameters describing thermo-mechanical behaviour of concrete and reinforcement are discussed. A powerful calculation technique based on layered approach is briefly described. Comparison of numerical simulation and test results has shown reasonable accuracy.
