| Abstract: | 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. |
