抗震设计中球罐固有频率的改进计算方法

Improved Calculation Method of the Natural Frequency of Spherical Tanks in Anti-Earthquake Design

对容积为50、100、…、1 000、5 200m3的拉杆型结构球罐的固有频率进行了计算分析,并根据现有公式拟合出改进的计算公式,改进前后的计算结果对比说明了此式的优越性。

A calculation analysis was made of the natural frequency of the pulling-rod type spherical tanks with volumes of 50,100,…, 1000, and 5 200m^3, and an improved calculation formula was fitted based on the existing formula, the calculation result comparison before and after the improvement shows that the advantages of the improved formula.
