| 摘 要： | 采用有限元方法 ,考虑在静载和动载共同作用下 ,对常压立式拱顶储油罐的地震应力进行了计算分析 ,给出了轴向应力的分布状态 ;并与相关抗震设计规范中的验算公式得出的结果进行了比较。结果表明 :由于地震的动力作用 ,储油罐的受力状态不是均匀分布 ,出现了峰值和谷值 ,而这些应力峰值大于工业设备抗震鉴定标准和石油化工设备抗震鉴定标准中公式的计算应力值 ,这应引起足够的注意。

| Abstract: | Considering common actions of static and dynamic loads, the seismic stress of vertical oil tank under normal pressure is calculated and analysed using finite element method, and the distribution condition of axial stress is given. Compared it with the result obtained from the related calculation formulation of anti earthquake design code, it is shown that the forced condition of the oil tank is inhomogeneous owing to the seismic dynamic action, there are the peak and valley values of seismic stress. It should be sufficiently noted that the stress peak value is bigger than the calculation one in aseismic assessment criterion of industry and petrochemical industry facilities. |
