In order to study the stability of the storage tank under strong wind load and ensure the safe operation of the oil tank, finite element analysis was used to solve the wind‐induced buckling mechanism of the 50000 m3 steel storage tank under wind load, and the stress stability of the storage tank under non‐standard conditions was analyzed. Numerical simulation is carried out, and it is calculated that the wind load pressure of the oil tank is mainly on the windward side with a circumferential angle of about 60°, and the wind pressure at the stagnation point is the largest; the analysis results can be used for the wind resistance stability design of large steel storage tank structures. provide a theoretical basis.
