Abstract:

In this study the dynamic buckling behaviour of anchored cylindrical steel tanks with different aspect ratios (H/D) under tri-directional seismic input is investigated using finite element method. Two anchored steel tank with different height to diameter (H/D) ratios is considered that are subjected to tri-directional ground excitations. The effect of aspect ratio of the tank models, type of seismic ground motions and importance of simultaneous 3-directional action of seismic ground motion on the seismic behaviour and formation of elastic and plastic buckling of steel tanks is investigated.The results obtained indicate the dominant effect of the aspect ratio and the type of ground motion on seismic response of steel tanks.
