- W122919263 abstract "BONO, G.F.F. Modelos Constitutivos para Analise Tridimensional de Estruturas de Concreto Armado atraves do Metodo dos Elementos Finitos. 2008. Tese (Doutorado em Engenharia) – Programa de Pos-Graduacao em Engenharia Civil, UFRGS, Porto Alegre. In this work, a 3D finite element model for analyses of reinforced concrete structures subjected to monotonic and cyclic loads is presented. The constitutive model proposed for the concrete is an orthotropic model that follows the nonlinear elasticity theory. In this model, the concept of equivalent uniaxial strain is applied for determination of the triaxial behavior of the concrete through three equivalent uniaxial stress-strain curves, which makes it easier to simulate the concrete’s behavior and allows a good approximation with experimental results. The model describes well the response of concrete when subjected to several loading types, being capable of representing crushing and cracking of concrete. The implementation in finite elements is based upon the consideration of smeared cracks with them rotating according to principal stresses’ directions. For simulation of the concrete’s behavior under cyclic loads, the modified Popovics-Saenz curve has been considered, with some changes in the coordinates of the origin and of the peak of this equivalent uniaxial stress-strain curve, when the concrete is subjected to unloading and reloading processes. The behavior of the steel is described by an uniaxial constitutive model. To model this behavior when subjected by monotonic loads, an elastic bilinear stress-strain curve with strain hardening is considered. For simulation of the cyclic response of the steel, a nonlinear constitutive model is used. This model can well represent the cyclic behavior of the steel, simulating its nonlinear response after load reversals. The computational code uses linear and quadratic isoparametric hexahedral finite elements for the concrete. To represent the reinforcing bars, an embedded model is used. Finally, to validate the efficiency of the proposed model, several numerical simulations are carried out in plain and reinforced concrete. The comparisons made with test results show an excellent agreement between the model predictions and experimental data." @default.
