摘要
本文以某实际工程为例,采用静力弹塑性分析方法,通过SAP2000进行Pushover分析,研究大跨度悬挑梁在地震作用下的结构抗震性能。通过在多遇和罕遇地震荷载作用下对结构的顶点位移、层间位移角以及塑性铰发展过程的研究,分析其抗震性能。同时研究不同悬挑长度对结构抗震性能的影响规律并提出相应的加固措施,可为今后类似结构的设计与抗震分析提供参考。
This paper takes a practical project as an example,using nonlinear static analysis method to researchcantilevered structure seismic performance under earthquake action.SAP2000 will be used for Pushover analysis.Thispaper analyzes the seismic performance of the structure through the top displacement,the interlayer displacementangle of the structure and the development of plastic hinges in frequently and seldom occurred earthquakes.Meanwhile,it studies the influence of different cantilever length on seismic performance of structures,and putsforward the corresponding reinforcement measures.Such being the case,this paper can provide reference for thedesign and seismic analysis of similar structure.
