Modélisation simplifiée 3D du comportement dynamique de structures en béton armé

ABSTRACT In the framework of the ECOLEADER program dynamic tests have been performed on the seismic table at the laboratory LNEC in Lisbon. The structure tested is a five floor building composed of two parallel walls linked with a perpendicular one that has openings. The scope of the experimental program is to evaluate the behaviour of this structure under bi-directional loading. Multifiber beams are used for the numerical model of the structure. Constitutive laws are based on plasticity for steel and damage mechanics for concrete. Comparison of the numerical and the experimental results shows the performance of the approach.
