王森，劉暢，魏璉，王志遠，周清曉（深圳市力鵬建筑結(jié)構(gòu)設(shè)計事務(wù)所，深圳 518034 ）［摘要］復雜的超限高層建筑結(jié)構(gòu)需要進行彈塑性分析和計算來驗證其是否滿足抗震設(shè)防要求。以珠海某復雜超限高層建筑工程為背景，對其進行彈塑性時程分析，研究該結(jié)構(gòu)在地震作用下的抗震性能。采用Perform-3D建立三維彈塑性分析模型，并進行了動力時程分析，對結(jié)構(gòu)在地震作用下的整體反應(yīng)和構(gòu)件損傷情況進行了分析和評估，用詳細的量化指標驗證了該結(jié)構(gòu)能夠在罕遇地震水平下實現(xiàn)“大震不倒”。結(jié)果表明，錯層并不會使剪力墻成為結(jié)構(gòu)受剪的薄弱環(huán)節(jié)。［關(guān)鍵詞］超限高層； 彈塑性時程分析； 抗震性能； 罕遇地震中圖分類號：TU311.3，TU313.3文獻標識碼：A文章編號：1002848X(2012)11004004Inelastic time-history analysis on a shear-wall structure with staggered floorsWang Sen, Liu Chang, Wei Lian, Wang Zhiyuan, Zhou Qingxiao（Shenzhen LIPENG Building Structnce Design Associates, Shenzhen 518034, China）Abstract: Inelastic analysis need be used to prove the safety of complex high-rise building structure under rare earthquakes. An inelastic time history analysis of a complex high-rise building with staggered shear-wall located in Zhuhai was carried out, and the seismic performance under different level earthquakes was studied. Perform-3D program was used to build analysis model and carry out time history analysis. The results were concluded in the entire structure response and the damage information of elements, and quantified the damage degree of this structure under rare earthquake, and verified that this structure would not collapse under rare earthquake.The soft shear floor is not formed in the structure.Keywords: high-rise building; inelastic time history analysis; seismic performance作者簡介：王森，博士，高級工程師,Email:ws2001622@163.com。參考文獻［1］ JGJ 3—2002 高層建筑混凝土結(jié)構(gòu)技術(shù)規(guī)程［S］.北京：中國建筑工業(yè)出版社，2002.［2］ 謝靖中，李國強. 錯層結(jié)構(gòu)的幾點分析［J］.建筑科學，2001,17(1):3537.［3］ 尹保江，龔思禮，程紹革.高層建筑中錯層剪力墻結(jié)構(gòu)的試驗研究［J］.建筑科學，1999,15(6):1820.［4］ Perform-3D user guide version4 ［M］.CSI.［5］ 魏璉.建筑結(jié)構(gòu)抗震設(shè)計［M］.北京：萬國學術(shù)出版社，1991.［6］ 劉暢，段小廿，魏璉，等.某超限高層結(jié)構(gòu)多程序彈塑性時程分析對比［J］.2012，42(11)：35-39,18.
