摘要
本文对塔型设备自振周期进行探讨，将现有常用理论公式的计算结构与实测进行对比，然后根据100台落地塔的实测周期，采用数理统计分析，提出计算自振周期的经验公式，并对经验公式作了分析。
The natural vibration period of columns was discussed in this paper. The calculation results form theory were compared with that from practical measurement.Some empirical formulas based on the statistics analysis then, were presented The results from these empirical formulas were analyzed finally.
