摘要：

A nonlinear finite element procedure for predicting the structural behavior of planar-reinforced planar-reinforced concrete members subjected to fire is described. The proposed procedure is based on an iterative, secant stiffness formulation. The complex features of structural behavior in fire conditions, such as thermal expansion, shrinkage, creep, cracking or crushing and change of material properties with temperature are considered. The spalling of concrete is excluded in this model. Predictions from the model proposed are compared against experimental results by previous researchers.
