中文摘要：
大跨连体结构是近二十年来发展起来的一种新型结构形式,受力性能较为复杂.以某高层大跨连体结构为背景,利用ANSYS软件建立三维有限元模型,从地震记录库中分别选取长周期地震波和普通地震波做为输入,采用大质量法对大跨连体结构进行了不同类型地震波作用下的行波效应分析与比较研究.结果表明：长周期地震波作用下大跨连体结构连廊杆件内力明显大于普通地震波作用下的结果;在纵向水平地震动激励下,横向水平杆的行波效应较明显,而竖向斜撑的行波效应影响较弱.
英文摘要：
Large-span connective structure is a new type of structure in recent twenty years,which is complexity of stress.Based on a high-rise large-span connective structure,long period seismic waves and normal seismic waves were chosen from the earthquake records as the input on a three-dimensional finite element model which was created with ANSYS software.And then,structures under Large Mass Method was used to analyze and make relative comparison of wave-passage effect on large-span connective structures under different types of seismic waves.The result shows that axial forces of the steel truss bars are obviously higher under long period seismic waves than normal seismic waves.Besides,the wave-passage effects of longitudinal bars are especially prominent while the wave-passage effects of diagonal bracings are quite weak under lateral excitations.
