THE CRITICAL INPUT WAVE FOR NON-LINEAR SYSTEM WITH ORIGINE ORIENTED HYSTERESES CONSIDERING PHASE PROPERTY : Part 2 The linear phase properties to the frequency for narrow frequency band wave

Abstract

A generation method of the input time history which causes the largest response to SDOF with origine-oriented hystereses is proposed. The linear phase property is extracted from waves generated with phases selected properly at the time of the reverse point of the response displacement and devel- oped to the generation method. Finally critical waves with the linear phase property are generated for two types of power spectra, one is smooth as Kanai-Tajimi power spectrum and the other is notchy as the spectrum of the recorded, and compared with those with rand am phases.
