A generation method of the input wave which causes the largest response to SDOF with origine-oriented hystereses is proposed. A uni-sinusoidal wave is selected to examine the phase effect on the inelastic response as a basic case , then it can be proved that the response becomes largest when the phase is selected properly at the time of the reverse point of the response displacement and this phase property can be applied to cases when the frequency is varied during the motion. Finally a critical wave with the Kanai-Tajimi power spectrum is generated as an example and its responses are compared with those with randam phases and those with phase properties specified in narrow frequency bands.
