| 摘 要： | 海洋平台上储罐的设计和计算以往都采用陆地上储罐的计算方法，这与实际情况有很大差别，也有人将储罐和内储液做为整个刚体来进行动力分析，这显然也是不合适的。本文将储罐及平台的结构体系简化成双自由度体系，用反应谱方法计算其地震反应，并建议了适合工程计算的简化方法。

| Abstract: | The design and the calculation of storage tanks erected on off shore platforms have so far been carried out by considering them as those on land.This,however,makes much difference to actual cases.It is apparently inappropriate to apply dynamic analysies to storage tanks and the liquid inside as complete rigid structures.The paper discusses the spectral method of reaction, with which seismic reaction is calculated by simplifying the structural system of storage tanks and platforms into the dual freedom system.The simplified methods for engineering calculations have also been recommended. |
