In numerous destructive earthquakes, a lot of building structures were obviously destroyed because of their irregular elevation. But with the continuous development of new shape-designing idea and the demands on different functions, vertically irregular building structures have been already unable to be totally avoided. In order to realize the influence of different kind of vertical irregularity on the earthquake response of building structures and the suitability of three types of such analysis methods as psuedo-static method, response spectrum method and linear time history analysis method and to guarantee the seismic safety of vertically irregular building structures, this thesis takes in six-floor building and 20-floor building for example and uses the SAP2000 analysis software to analyze and investigate the characteristics of earthquake response of such four types of building structures as regularity, vertical geometry irregularity, vertical stiffness irregularity and vertical mass irregularity. Further more this thesis investigates the suitability of such three types of analysis methods as psuedo-static method, response spectrum method and linear time history analysis method.
The results of this study have shown that among vertically irregular building structures, the influences of geometry irregularity and stiffness irregularity on the earthquake response are more and the influences of mass irregularity is smaller. Besides, for low-rise and high-rise building structures, the results got by response spectrum method and linear time history analysis method are similar. For low-rise building structures, psuedo-static method is still applicable in the earthquake response analysis of vertically irregular building structures, but psuedo-static method is not suitable for high-rise building analysis.
