1、在建筑物的地震易損性分析中,人們常采用基于概率的抗震需求譜來進(jìn)行,而云分析是常用的一種方法。在云分析方法中,統(tǒng)計(jì)模型用來預(yù)測(cè)建筑物在地面地震強(qiáng)度下的需求。這些模型的地震破壞參數(shù)(EDP s)等數(shù)據(jù),通過建筑物在一組不同烈度(IM)地震動(dòng)下的動(dòng)態(tài)或靜態(tài)非線性分析獲得。統(tǒng)計(jì)模型得到了任意強(qiáng)度IM下的地震損傷指數(shù)(EDP),并給出不同記錄間的差異。
本論文通過在動(dòng)力非線性分析中考慮記錄間的差異及參數(shù)的不確定性,提出一種擴(kuò)展的云分析方
2、法。案例研究通過一個(gè)三跨四層的鋼筋混凝土建筑,滿足歐洲抗震規(guī)范的設(shè)計(jì)。采用的EDP為樓層最大層間位移,此指標(biāo)可由Opensees軟件計(jì)算獲得。參數(shù)不確定性主要考慮了混凝土軸心抗壓強(qiáng)度變化C30/37以及S450鋼材的屈服強(qiáng)度變化。采用蒙特卡洛方法研究從模型參數(shù)到EDP指標(biāo)間的不確定性,并采用常用的克里格替代模型來大幅減少動(dòng)力非線性分析的計(jì)算成本。對(duì)比考慮這些參數(shù)不確定性及不考慮參數(shù)不確定性的云分析結(jié)果,可以得到基于性能的抗震設(shè)計(jì)中較感興
