| 摘 要： | 本文根据双曲冷却塔旋转壳在建造中将产生随机几何缺陷这一特点,对具有一般随机几何缺陷旋转壳的动力特性进行了分析。结果表明,考虑随机几何缺陷后,系统的低阶固有频率将降低,内力阵风响应因子将升高。

| Abstract: | In this paper, dynamic characteristics of a rotational shell having random geometric imperfections are analysed, as viewed from its engineering structure. It is shown that, the basic natural frequency will decrease and the internal force response factor will increase if the random geometric imperfections are taken into consideration. |

| Keywords: | rotational shell random geometric imperfections cooling tower wind response. |
