摘　　要：为研究大型钢制储罐在风荷载作用下的力学特性,借助有限元软件ABAQUS,建立了静力风荷载作用下储罐有限元模型,对比分析裸罐(不含抗风结构)与加强罐(含抗风结构)在风荷载作用下迎风面与侧风面罐壁的应力与变形结果,以及储液对储罐抗风性能的影响。结果表明:迎风面罐壁受风压力作用,罐壁内凹,侧风面罐壁受风吸力影响,罐壁外凸;风荷载对空罐影响较大,抗风结构可以有效地减弱空罐状态下罐壁顶部的变形;充液状态下,风荷载对罐壁的作用效果不明显,在储液压力作用下罐壁最容易破坏的位置出现在距离罐底高度2.42 m处。This paper aims to investigate the mechanical properties of large steel storage tanks under wind loads.The study is enabled by establishing a finite element model of the storage tank under static wind load with the help of the finite element software ABAQUS,comparing and analyzing the stress and deformation results on the windward side and crosswind side of bare tank(without wind-resistant structure) and reinforced tank(with wind-resistant structure) under wind load,and the influence of storage liquid on the wind-resistant performance of the storage tank.The results show that the tank wall is concave on the windward side by wind pressure,and the tank wall on the crosswind side is convex by wind suction.The wind load has a great influence on the empty tank,and the wind-resistant structure can effectively reduce the deformation of the top of the tank wall in the empty tank state.In the liquid-filled state,the effect of wind load on the tank wall is not obvious,and the most easily damaged position of the tank wall under the action of storage pressure appears at a height of 2.42 m from the bottom of the tank.
