摘      要：This paper studies the dynamic responses of SDOF system under pulse-dominant *** purpose of the study is to prepare for scrutiny of some near-field pulse-dominantground motions and their potential to cause structural *** the single pulse dynamics,we consider the effect of pulse *** kind of excitation was particularly obvious in some of previous earthquakes such as Northridge (1994) and Chi-Chi (1995).Based on the duration, peak and rise and decay era of the main pulse as well as its relationship with the predecessor and successor pulses,we propose a classification for the pulse *** studies have been canied out for acceleration,velocity and displacement response spectra of the main pulse with either a predecessor or a successor *** analysis also includes general response behaviors in different fundamental period segments and special aspects of response at certain points (e.g.,the corresponding peak points).
