摘要
通过不同的方法,对多种规格球罐整体结构的自振周期及地震响应进行分析计算,发现球罐设计标准GB 12337的计算误差较大,《压力容器》杂志2006年第3期上发表的《球罐整体结构水平刚度及支柱拉杆应力分析》一文中介绍的方法的计算结果与有限元模态分析计算结果较吻合。
Natural period of vibration and response analysis of seismic force of several spherical tanks were analysed and calculated through different methods.We find that the results of design standard GB 12337 have great error,and the results of reference ＂Horizontal Stiffness of Spherical Tank as a Whole and Stress Analysis of Tie-rod Between Support Columns＂ are close to the results of finite element modal analysis.
