　　主要研究了大型石油储罐在风载荷作用下的响应。首先，介绍了风载荷分析时用到的风压模型，并建立了储罐的有限元模型；然后，对储罐进行了模态分析；最后，分别计算了储罐在静态风压和动态风压模型下的响应。结果表明：储罐的模态呈多波分布，该振动为储罐周向振动和竖向振动的叠加。在静态风压模型下，储罐的最大位移发生在靠近储罐罐顶的罐壁某处；最大应力发生在罐壁与地板的连接处。在动态风压模型下，动态响应的峰值（如位移和应力峰值）延迟于风载荷峰值的出现。

This work was to study the response of large scale oil storage tanks subjected to wind load . Firstly,the wind pressure model and the finite element model of the tank were introduced .Then,modal a-nalysis was conducted .Finally, wind responses of the tank under the static and dynamic wind pressure models were studied .The results show that the vibration is the mutil -wave vibration ,which is the super-position of the circumferential and vertical vibrations .For the tank under the static wind pressure ,maxi-mum displacement occurs on the tank wall close to the top edge , while maximum stress happens on the joint between the bottom plate and the tank wall .For the tank under the dynamic wind pressure ,there is a time delay between the peak response (e.g.displacement and stress ) and the maximum load.
