【摘要】：提出一種概率地震需求分析的云圖-條帶法。該方法通過(guò)引入經(jīng)驗(yàn)地震易損性分析中的數(shù)據(jù)處理方法,解決傳統(tǒng)云圖法無(wú)法處理海量非線性時(shí)程分析結(jié)果的局限。為說(shuō)明該文提出方法,選取100條地震動(dòng)作為輸入,針對(duì)23個(gè)鋼筋混凝土框架結(jié)構(gòu)進(jìn)行了云圖法分析�；谒薪Y(jié)構(gòu)的云圖結(jié)果,采用云圖-條帶法建立了群體結(jié)構(gòu)的概率地震需求模型,并計(jì)算得到了群體結(jié)構(gòu)的地震易損性。研究表明:云圖-條帶法可以有效地處理海量非線性時(shí)程分析結(jié)果,建立較為合理的概率地震需求模型。在輸入地震動(dòng)的強(qiáng)度范圍內(nèi),群體結(jié)構(gòu)整體發(fā)生嚴(yán)重破壞和完全破壞的概率很低,而主要以發(fā)生輕微破壞和中等破壞為主。
[Abstract]:A cloud map strip method for probabilistic seismic requirement analysis is proposed, in which the data processing method of empirical seismic vulnerability analysis is introduced. To solve the limitation that the traditional cloud map method can not deal with the results of massive nonlinear time-history analysis, 100 ground motions are selected as input to illustrate the method in this paper. The cloud map method is used to analyze 23 reinforced concrete frame structures. Based on the cloud map results of all structures, the probabilistic seismic demand model of group structures is established by using the cloud graph-strip method. The seismic vulnerability of group structure is calculated. The results show that the cloud map and strip method can effectively deal with the results of massive nonlinear time-history analysis and establish a more reasonable probabilistic seismic demand model. The probability of serious and complete destruction of the whole population structure is very low, but mainly of slight and moderate destruction.
