为了给大型储罐地震动力响应进一步分析提供数据,建立了大型储罐有限元简化模型,考虑了罐体的固液耦合作用,对储罐系统的自振特性进行了分析,结果表明,有限元结果与规范计算结果误差很小,计算结果可靠。%In order to provide further data about the seismic dynamic response of the large storage tanks,the paper establishes the finite simplified models of the large storage tank,considers the solid-liquid coupling effect of the tanks,analyzes the natural vibration features of large-scale storage tanks,and proves by the results that the errors between the finite element results and the regulated calculation ones are little,so the calculation result is reliable.
