Abstract

Within the framework of the TMR - ICONS research program, dynamic and cyclic tests on U- shaped shear walls have been performed at CEA Saclay and JRC Ispra respectively. The paper presents the simulations made at LMT Cachan in order to prepare the tests and the comparisons between the numerical and the experimental results. 2D multi-layered Bernoulli beam elements and uniaxial constitutive laws based on damage mechanics and plasticity have been used to define the seismic intensity levels to be applied during the shaking-table tests. In order to simulate the cyclic tests a 3D multifiber Timoshenko beam element with higher order interpolation functions has been developed. Comparison with the experimental results shows the well funding and the limitations of the two approaches.
