摘　　要：对于薄壳结构这种区别于传统房建的结构,通过脉动法测定其不同部位的频率,试图从整体上把握这种结构的整体刚度,为其结构的安全性鉴定作有益的补充。The shell structure is different from the traditional housing in the structure determination. We detect different part of the structure of frequency by pulsating method, attempt to grasp the integral rigidity of this structure as a useful complement for the overall stiffness of the structural safety of its identification.

关 键 词：薄壳结构 鉴定 脉动法 频率
