基于Pushover方法的多高层钢结构的抗震研究
|
摘要
随着基于性能的设计思想在结构抗震设计中的提出和发展,Pushover分析方法得到地震工程界的广泛兴趣和重视。Pushover分析方法是一种静力弹塑性方法,由于具有概念清晰、简便实用等特点,已成为结构抗震设计和分析的重要方法。使用该方法可以获得结构弹塑性状态下的强度和变形,同时可以找出结构的薄弱环节,已逐渐被认为是基于性能设计中的一个重要工具。
本文首先对Pushover分析方法的发展和研究现状以及理论背景、基本假定做了论述;在此基础上应用Sap2000有限元分析软件,考虑不同的水平加载模式对多层和高层钢框架结构进行了多遇地震和罕遇地震作用下的Pushover分析,得到结构顶点位移、楼层位移和层间位移角等结果,对结构的抗震性能进行多方面的评估,验证了Pushover分析方法的正确性和可靠性。对相同的结构模型又进行了反应谱分析和时程分析,通过三种分析结果的比较,探讨Pushover分析在高层建筑结构抗震性能分析中的适用性,为进一步研究和完善该方法在高层建筑结构领域中的应用提供依据。
With the proposal and development of the performance-based design theory,pushover analysis method has been widely caught interesting and attention in the earthquake engineering. Pushover analysis method is a static elasto-plastic method and has become an important structural seismic design and analysis method due to its practicality and simplicity. Pushover analysis method is gradually deemed to an important tool for the performance-based seismic design because it can get the strength and deformation when the structure is in nonlinear state and also find out the weakness of the structure.
In this thesis, the development and current research situation,the theory foundation and the basic hypothesis of the pushover analysis method are first described.Then the pushover analysis method is adopted with the aid of the SAP2000 software to analyze the multi-layer and high-rise steel structure in small earthquake and rare earthquake.In the analysis various lateral loading patterns are considered and the corresponding results including the nonlinear top-story displacement, story displacement and the distribution of story drifts are obtained.Based on the obtained results the seismic resistance of the structure is evaluated and correction and reliability of the pushover analysis method are validated.The response spectrum analysis and the elasto-plastic time-history analysis are used to analyze the same structure models and obtain results.For supplying evidences to improve the research of pushover method's application,the results from the above three analysis methods are compired and pushover method's application in the seismic performance analysis of high-rise structure is discussed.
