摘要:
对同济大学强震监测台在汶川地震中测得的地震记录进行频谱特性分析,以同济大学教学科研综合楼为研究对象,应用通用有限元软件建立计算模型,分析了该结构在这一实测地震记录作用下的响应特点,并将其与调幅后的El Centro波、Taft波和上海人工波作用下的计算结果进行了对比分析,同时探讨了远震对深覆盖场地上高层建筑的影响。结果表明:尽管汶川地震同济波的峰值加速度很小,但是2～3.5 s的长周期分量卓越性却十分突出,共振效应造成长周期的高层建筑地震反应明显。
Abstract:
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.
