摘要
为研究高层结构在地震作用下的抗震性能,文中以某15层高层剪力墙结构为主要研究对象,利用ABAQUS有限元软件,构建了有限元模型,并进行模态分析与动力时程研究,通过输入3条8度罕遇强度等级的地震波作用,确定了结构在大地震影响下的震害动力响应,得出其最大层间位移角在规范限值以内,结构满足大震不倒的抗震设防要求,以此确定结构的可靠性.
Abstract
This paper studies the seismic performance of high-rise structures under earthquake action.The finite el-ement model of a 15-story high-rise shear wall structure is established by ABAQUS software,and the modal analy-sis and dynamic time are conducted.By inputting three seismic waves with rare intensity levels of 8 degrees,the seis-mic dynamic response of the structure under the influence of a large earthquake is determined,and the maximum in-ter story displacement angle is within the specification limit,which not only meets the seismic fortification require-ments of not collapsing during a large earthquake,but also determines the reliability of the structure.
