Comportamento não-linear de estruturas de concreto armado com aplicação a análise de vasos de pressão de usinas nucleares

The formulation and numerical implementation of a concrete model that has been incorporated in the computer program LORANE-NL has been presented. The material model is a hypoelastic model based on a nonlinear uniaxial stress-strain relation that is generalized to take account biaxial and triaxial stress conditions. Tensile cracking, compression crushing and cyclic loading conditions are considered. Steel reinforcement has been modeled by discrete nonlinear spring elements. The results of various sample analysis are given, in which the stability and accuracy of the finite element representations by four to eight node isoparametric quadrilateral elements have been studied.
