Most of these are based on the tank parameters(参数) in the design stage. It focuses on the infuence of the imperfection or the reinforcement device on the buckling behavior of empty tanks under the wind load. However, in-service tanks almost have installed diferent size parameters of reinforcement devices. And before weather disasters such as typhoons(台风) or strong winds arrive, the storage state of the tank is often not simply empty or full. Therefore, depending on the numerical simulation method recommended(推荐) by EN1993-1-6 [16], linear buckling analysis and geometrically nonlinear buckling analysis, this paper explored the buckling behavior of each storage tank under wind load. And study the strengthening mechanism of stored liquid to in-service storage tanks and the infuence of reinforcement devices on the buckling behavior of storage tanks.
