Extensive validation of the SSI macro element using experimental and numerical results

This paper presents simulations concerning the numerical modelling of a seven story building tested on a shaking table considering different boundary conditions. At first, the structure is supposed embedded in the shaking table and is discretised using multifiber Timoshenko beams. Comparisons with experimental results are given. Then further simulations are made considering soil structure interaction (SSI) and different types of soils or base isolators. It is shown that the proposed modelling strategy describes accurately the global behaviour of the structure and qualitatively the distribution of damage for all different configurations.
