There have been numerous proposals for predicting maximum deformations of SDOF systems without doing non-linear time history analyses. Among them is Capacity Spectrum Method, where the system is assumed to deflect symmetrically. But this is not reality. This paper describes the causes of asymmetric response using the rigid-plastic model. One of the causes is the asymmetry of ground acceleration. The other is the hysteretic property of the models. A comparison with the elasto-plastic and Takeda models is also presented.
