摘　　要：本文利用拟壳法研究了双曲率网状扁壳的动力问题。以两个双重级数为试函数，求得了四边简支边界条件下双曲率网状扁壳固有频率的计算公式。在考虑阻尼力的情况下，求得了双曲率网状扁壳竖向地震响应的解，并且计算公式中的系数可从《建筑抗震设计规范（ＧＢＪ１１－８９）》规定的设计反应谱求得。本方法计算简便，电算手算均可。In this paper, the dynamic problems of hyperboloid latticed flat shells are studied by using the method of simulated shell. In the case of simply supported latticed flat shells, the frequency equation is derived by using two functions of a double trigonometric series. When considering the damping forces, solutions of the vertical seismic responses of hyperboloid latticed flat shells are given and the coefficient in the formulas can be obtained by using the design response spectrum of the Standard GBJ 11 89. Numerical examples show that this method is simple.
