Simulaçao numérica do comportamento de vigas e pilares de concreto armado via mef usando o código CASTEM 2000

Abstract

The objective of this paper is the numerical sttudy of the behavior concrete beams and columns by non-linear numerical simulations. The numerical analysis is based on the finite element method implemented in CASTEM 2000. This program uses the constitutive elestoplastic perfect model for the stee, the Drucker-Prager model for the concrete and the Newton-Raphson for the solution of non-linear systems. This work concentrates on the determination of equilibrium curves to the beams and force-strain curves to the columns. The numeric responses are confronted with experimental results found in the literature in order to check the reliability of the numerical analyses.
