［摘要］动力弹塑性分析方法是结构分析技术发展的重要成果之一，也是数值仿真技术在工程领域的典型应用，目前已成为性能化抗震设计方法中的重要组成部分。但是由于其涉及到的理论知识、技术方法以及软件应用等均不同于传统的静力或者线性分析方法，一线工程师通常难以了解掌握。以数值仿真技术特征为切入点，从数值模型建立、数值分析方法、分析结果解读等几方面，探讨了动力弹塑性分析方法及其在结构设计中的应用，并以ABAQUS软件平台为例，介绍了结构整体弹塑性数值模型的建立方法，以及结构整体与构件分析结果的输出与解读。

Abstract:The dynamic elasticplastic analysis method is one of the major advancements in structural analysis technology in particular and is  also a typical application of  numerical simulation technology in engineering. It has been a key component in the performance-based seismic design methodology. However, this advanced analysis method may not be easily understood by structural engineers working in design firms, because theoretical knowledge, technical methods and software application required in this method are different from those in conventional static and linear analysis methods. Starting from the numerical simulation technical characteristics, the numerical model establishment, numerical analysis method and the interpretation of the results were introduced, to discuss the dynamic elastic-plastic analysis method and its application in structural design. And with ABAQUS software platform as an example, the establishing method of structural overall elasticplastic numerical model was introduced as well as the output and interpretation of analysis results of the whole structure and the components.

Keywords:dynamic elasticplastic analysis; performancebased design; numerical model; analytical method; interpretation of results
