Application of Two Response Spectrum Analysis Methods from RG1.92 for Steel Frame
-
摘要: RG1.92(2006版)为了考虑反应谱分析高频部分的质量丢失问题,将核电厂结构、系统和组件的地震响应分为2个部分:周期性反应和刚性反应。核电厂安全壳内的钢平台地震响应包括刚性反应和周期性反应,需要将刚性反应和周期性反应剥离开来分别计算。分别使用Gupta法+Missing Mass法和Lindley-Yow法+静态零周期加速度(ZPA)法,通过GTStrudl软件的程序语言编制满足这2种组合方法要求的计算程序,以一个钢平台为实例,对比研究2种谱分析方法在实际应用中的差异,确定核电厂安全壳内的钢平台分析设计采用的反应谱分析方法。Abstract: In order to consider mass lose of frequency part of reaction response analysis, RG1.92（2006）separate nuclear power plant structure, systems, and components（SSCs） into two parts, which are referred to as the "periodic" response and the "rigid" response. Modes of steel frames in the containment vessel distribute in the periodic response region and rigid response region. A response spectrum analysis on a steel frame inside the containment is performed based on Gupta +Missing Mass and Lindley-Yow +ZPA to study the difference of the two methods. The software GTStrudl is used to perform the spectrum analysis based on the two methods above and to find a better way to complete the calculation of Steel frames in containment vessel.
