［摘要］高層結(jié)構(gòu)在罕遇地震作用下的動(dòng)力彈塑性分析已經(jīng)成為土木工程領(lǐng)域的研究熱點(diǎn)。然而對(duì)復(fù)雜結(jié)構(gòu)進(jìn)行有限元建模時(shí)，由于不同軟件關(guān)鍵技術(shù)的假設(shè)與條件不同，導(dǎo)致對(duì)于同一結(jié)構(gòu)采用不同軟件計(jì)算時(shí)結(jié)果差異較大。以國(guó)內(nèi)外廣泛使用的PERFORM-3D與ABAQUS軟件為例，深入探討了單元類型、連梁模擬、積分算法與結(jié)構(gòu)阻尼等關(guān)鍵因素，以解決目前動(dòng)力彈塑性分析結(jié)果的離散性問(wèn)題，使不同軟件數(shù)值計(jì)算結(jié)果更為可靠，結(jié)果對(duì)比更有價(jià)值。［關(guān)鍵詞］高層建筑; 時(shí)程分析; PERFORM-3D軟件; ABAQUS軟件中圖分類號(hào)：TU313.3 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：1002-848X(2015)23-0059-06
Dynamic time-history analysis of high-rise structure based on PERFORM-3D and ABAQUSWang Changxing, Wang Dongfang, Fu Xuebao, Chen Chuncai(Materials Saving Research and Structural Optimization Center, Beijing Tsinghua Urban Planning and Design Institute, Beijing 100083, China)Abstract: The dynamic elastic-plastic analysis of high-rise structure exposed to severe earthquake has been a research focus in the civil engineering field. However, the hypothesis and conditions for finite element model of complex structure are different in various software, which lead to large differences among the calculation results of the same structure calculated by different software. Taking the PERFORM-3D and ABAQUS software widely used at home and abroad for example, the element type, link beam model, integration algorithm, structure damp were discussed to solve the discreteness problem of present dynamic elastic-plastic analysis and improve the calculation reliability, which can make the analysis result calculated by different software be more valuable.Keywords: high-rise structure; time-history analysis; PERFORM-3D software; ABAQUS software
