摘要
本文运用反应谱分析方法 ,对具有多材料、多阻尼特点的沉箱式结构——某电站前池边墙 ,进行了三维有限元抗震分析 ,得到了供设计参考使用的结构内力分布曲线。本文同时还将该结构简化为三种平面计算模型 ,对接触面效应及材料参数折算等数值进行了处理 ,并将其反应谱分析的结果与三维分析的结果比较 。
Employing the method of seismic spectrum analysis,the caisson type structure with multi material and multi damping in the power plant is analyzed by three dimensional finite element computation.The distributions of internal force and moment which are referenced for seismic design are obtained.The caisson type structure is also simplified to three kinds of plane strain problems to perform easier and quicker seismic spectrum analysis.The Interface behavior,conversion of material constants and other numerical techniques are treated in the paper.With comparing results from three dimensional and two dimensional analysis,the simplified plane analysis for the caisson type structure is recommended.
