| 摘 要： | 进行推覆分析研究的目的就是要简化实际工程分析,并能真正的把它用于指导实际工程设计。本着这一宗旨,提出应用等效单自由度体系直接求多自由度体系在地震作用下目标位移的简化公式,同时就其中的一些修正系数的表达式及其取值进行了深入的研究;应用提出的简化方法,可以避免实际工程中复杂的弹塑性动力时程分析,提高工程分析的效率。

| Abstract: | The purpose of the study on the nonlinear static analysis is to simplify the practical engineering analysis and use its result to guide the practical engineering design.To achieve this aim,a simplified equation is proposed in this paper and a parameter study is conducted to get the rational coefficient values in the equation.At the same time the target displacement of a MDOF(Multiple degree of freedom)structure under design earthquake can be obtained from its equivalent SDOF(Single degree of freedom)system.The analysis of a practical engineering structure with the simplified equation proposed in this paper is more efficient than with the traditional one,and the complex nonlinear dynamic history analysis procedure is avoided. |

| Keywords: | nonlinear static analysis equivalent SDOF system target displacement correcting coefficient simplified methods |
