Dynamic buckling of cylindrical storage tanks under fluctuating wind loading

The present paper investigates the wind-induced buckling and vibration of cylindrical storage tanks based on wind tunnel experiments and time-history response analysis. Focus is on the effect of the vibration of tank shells on the buckling behavior. The dynamic buckling loads obtained from the experiments and the time-history response analysis are compared with the results obtained from the static buckling analysis. The effect of the inertia force generated by the vibration on the dynamic buckling behavior is found to be fairly small. Finally, the dynamic buckling loads are evaluated based on the results of the analysis for static wind loading. (100 words). •Wind-induced buckling of cylindrical storage tanks are investigated.
