摘要
本文研究了高压电气设备的抗震可靠度分析问题。采用具有柔性节点有限元法进行设备的地震动力反应分析 ,在此基础上利用反谱分析理论 ,建议了一类简化的抗震可靠度分析方法。通过对典型电气设备的分析 ,给出了设备在不同场地土条件和不同地震烈度下的可靠度和失效概率 。
Problems of seismic reliability analysis are studied in this paper.The finite element method with flexible joints is applied to analyze the seismic response of the electrical installations.On such basis,the response spectrum analysis was used and a simplified method of seismic reliability analysis was suggested.Through the analysis of typical electrical installations,the reliability and failure probability of the installations under different site conditions and earthquake intensities are given by calculation.Results show that the method suggested by this paper is effective and practical in use.
