This paper summarizes a study that aim to clarify the relation between the asymmetric response of the SDOF systems and the ground motion characteristics. The asymmetric response is affected by the ground acceleration more than the ground velocity. Rigid-Plastic Response Spectrum, which is newly defined as the relation between the base shear forces and maximum deformation of the rigid-plastic model, is useful to evaluate the effect of the ground motion on the asymmetric response of the elasto-plastic model.
