Nonlinear numerical analysis of reinforced concrete beams under high temperature

Abstract

Reinforced concrete structures subjected to fire will generally experience complex behaviour. This paper presents a strategy of numerical simulation of reinforced concrete members exposed to high temperatures and subjected to external loading. Finite element modelling of full load – deflection behaviour of experimental reinforced concrete beams reported in the literature has been carried out by the FE software ATENA. A constitutive model based on Eurocode 2 specifications has been used in the analysis. Comparison of numerical simulation and test results has been carried out.
