Dynamic Response Analysis of High-rise Buildings in Shanghai During Wenchuan Earthquake

The characteristics of frequency spectrum of seismic acceleration records during Wenchuan Earthquake obtained by the strong earthquake monitoring station in Tongji University were analyzed.Then,the seismic responses of the Teaching and Research Building in Tongji University were computed based on a calculating model in the finite element software.Furthermore,the results were compared with those data produced under amplitude modulated El Centro wave,Taft wave and Shanghai artificial wave.Finally,authors essentially discussed the effect of a distant earthquake on the high-rise buildings over the deep overburden site.The results show that long period component in Tongji wave in Wenchuan Earthquake is very remarkable.Therefore,the resonance effect leads to obvious seismic responses of the high-rise buildings with long fundamental period although its peak acceleration is very small.
