000011862 520__ $$2eng$$aThe torsional response of base-isolated structures with bilinear hysteretic behavior when eccentricities are set in the superstructure is presented. Nonlinear dynamic analyses were used to study peak responses for different ratios of the static eccentricities (es) between the centers of mass and the centers of rigidity of the superstructure, due to asymmetries in the stiffnesses of the structural elements. Among other relevant issues, it was found that torsional amplifications due to an asymmetric distribution of the masses in the superstructure are higher than those due to asymmetries in the stiffnesses of the structural elements for all the TI/Tb ratios considered in the effective base-isolated period range under consideration.
