| 摘 要： | 静力弹塑性分析方法（Push-over分析方法）是一种简化的非线性分析方法，动力弹塑性分析方法是目前公认的一种准确分析方法，本文将二者的优点结合起来，研究了静动力综合法的原理和分析过程。文中首先介绍了退化三线型恢复力模型的基本原理，在此基础上研究了静动力综合法的主要实施过程。然后，对两个混凝土框架结构进行了静动力综合法的分析，并与弹塑性时程分析结果对比，结果表明该方法有较好的精度。

| Abstract: | Static elastic-plastic analysis method （ Push-over analysis method ） is a simplified nonlinear method and dynamic elastic-plastic analysis method is a accepted accurate analysis method at present. This paper studied the principle and analysis process of static-dynamic analysis method by combining both advantages. Firstly, main implementing process of static-dynamic analysis method was studied in this paper based on the theory of three linear forcerestoring model. Then static-dynamic analysis of two concrete frame structure was made and the outcome was compared to the results of elastic-plastic time-history analysis which indicate that this method has high accuracy. |
