【摘要】：地震是一種突發(fā)式的自然災害給人類社會帶來災難造成不同程度的人身傷亡和經(jīng)濟損失。我國地震斷裂帶分布廣泛,同時也是世界上遭受地震危害較重的國家之一。隨著我國社會科技和經(jīng)濟的迅猛發(fā)展,高層建筑在我國的發(fā)展非常迅速,對高層建筑而言,地震作用是結構計算分析的主要控制因素,因此,對結構抗震計算的分析方法也在不斷地研究和改進。靜力彈塑性Pushover分析方法是當前主要使用的方法之一,它將結構靜力彈塑性分析與地震反應譜結合起來,在一定條件下簡單有效地評價結構抗震能力。目前已得到推廣應用并被列入我國建筑抗震設計規(guī)范中。 本文介紹了近年來國內(nèi)外對靜力彈塑性分析方法的研究發(fā)展現(xiàn)狀、靜力彈塑性Pushover分析方法的基本含義；通過采用MIDAS/Gen、ETABAS兩種計算程序對復雜超限結構工程進行超限審查分析,并論述靜力彈塑性Pushover分析方法的優(yōu)點、局限性、應用背景、基本原理、靜力彈塑性Pushover分析方法注意問題。本文采用MIDAS/Gen程對工程實例進行靜力彈塑性Pushover分析,得到能力譜曲線、結構達到性能點時的層間位移和層間位移角以及塑性鉸發(fā)展圖,從而判斷結構的薄弱部位,結構的抗震承載能力是否能夠達到在不可知地震發(fā)生時結構的性能目標。同時驗證Pushover分析方法在結構抗震分析中的可行性。通過本文對超限結構靜力彈塑性Pushover分析方法的研究得出結論和展望,對超限結構在工程中的分析具有一定的參考價值及指導意義。
[Abstract]:Earthquake is a kind of sudden natural disaster that brings disaster to human society, resulting in different degrees of casualties and economic losses.The earthquake fault zone is widely distributed in China, and is also one of the countries that suffer more serious earthquake damage in the world.With the rapid development of social science, technology and economy in our country, high-rise buildings are developing very rapidly. For high-rise buildings, seismic action is the main controlling factor of structural calculation and analysis.The analytical method of seismic calculation of structures is also being studied and improved continuously.Static elastoplastic Pushover analysis method is one of the main methods used at present. It combines static elastoplastic analysis with seismic response spectrum to evaluate the seismic capacity of the structure under certain conditions.At present, it has been popularized and included in the code for seismic design of buildings in China.This paper introduces the research and development of static elastoplastic analysis methods at home and abroad in recent years, the basic meaning of static elastic-plastic Pushover analysis method, and the analysis of complex over-limit structures by using Midas / Genestra ETABAS two kinds of calculation programs.The advantages, limitations, application background and basic principles of the static elastoplastic Pushover analysis method are discussed. The attention of the static elastoplastic Pushover analysis method is also discussed.In this paper, the static elastoplastic Pushover analysis of engineering example is carried out by using MIDAS/Gen equation, and the capability spectrum curve is obtained, the interstory displacement and the interstory displacement angle and the plastic hinge development diagram when the structure reaches the performance point are obtained, so as to judge the weak position of the structure.Whether the seismic bearing capacity of the structure can achieve the performance goal of the structure in the event of unknown earthquake.At the same time, the feasibility of Pushover analysis method in seismic analysis of structures is verified.In this paper, the conclusion and prospect of the static elastoplastic Pushover analysis method for the over-limit structure are obtained, which has certain reference value and guiding significance for the analysis of the over-limit structure in the engineering.
