Abstract:
A nonlinear layered finite element procedure for predicting the structural response of reinforced concrete slabs subjected to fire is described. The proposed procedure is based on the Mindlin/Reissner (thick plate) theory and an iterative, tangent stiffness formulation is employed. The complex features of structural behavior in fire conditions, such as thermal expansion, cracking or crushing, and change of material properties with temperature are considered, but spalling of concrete is excluded. Predictions from the model are compared against experimental results by previous researchers.
