矩形域上双曲扁壳的动力分析

Dynamic Analysis of a Simply Supported Hypar Shallow Shell

由壳体振动的控制方程出发,在四边简支的边界条件下,借助两个双重级数给出矩形域上双曲扁壳在任意激励下的解析解以及自由振动时的频率公式,进而给出地震力作用下双曲扁壳的动位移和应力函数表达式.

7his paper presents the analytical solution of the dynamic response of a simply supported hypar shallow shell under excitation based on the fundamental ribration eaquation and used two double trigonometic, serise and dirac δ function. When earthquake force is applied on the hypar shallow shell, the Solution would be given similarly.
