The highly asymmetric structure usually exhibits significant torsional effects arising from the non-coincidence of mass- and shear centers, when subjected to a strong ground excitation. Since both the magnitude and the orientation of structural eccentricity are not only dependent upon the layout of inner shear walls but also closely related to the outer geometric pattern of the structure, a multistory walled building with an L-type configuration is hence chosen as the target investigated herein so as to recognize the correlation between structural seismic behaviors and some crucial parameters. To acquire the satisfactory analytical results the degenerated shell element and a sophisticated 3-D soil-structure interaction model will be, respectively, used for modeling the slab and reinforced shear walls and for simulating the interaction forces between the structure and the soil. Furthermore, in order to obtain more realistic solutions, the influences of the substructure and the soil property on the torsional responses of the global system will be also investigated in detail.
