Abstract

A complete method to predict the behavior of reinforced concrete structures with beams and columns controlled by flexure is proposed. The concrete is modelled with a damage mechanics approach. The parameters of the model are adjusted on material tests and various procedures that account for confinement and cyclic response. Steel is modelled with a simple cyclic model. A simplified finite element program allows the prediction of the global and the local behavior from the constitutive laws of the material. This program uses multilayer beam elements. Localization of damage for softening structures is taken into consideration by a meshing procedure. The methodology is used to predict the behavior of three different kinds of structures subjected to three different types of loading. Predictions are in very good agreement with experimental results.
