［摘要］高层结构在罕遇地震作用下的动力弹塑性分析已经成为土木工程领域的研究热点。然而对复杂结构进行有限元建模时，由于不同软件关键技术的假设与条件不同，导致对于同一结构采用不同软件计算时结果差异较大。以国内外广泛使用的PERFORM-3D与ABAQUS软件为例，深入探讨了单元类型、连梁模拟、积分算法与结构阻尼等关键因素，以解决目前动力弹塑性分析结果的离散性问题，使不同软件数值计算结果更为可靠，结果对比更有价值。［关键词］高层建筑; 时程分析; PERFORM-3D软件; ABAQUS软件中图分类号：TU313.3 文献标识码：A 文章编号：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
