摘要: The main focus of the current study is to evaluate performance elevated tanks under seismic loading. In this study, finite element (FE) technique used investigate response liquid-filled tanks. fluid domain modeled using displacement-based elements. Both time history and modal analyses are performed on an tank. Using FE technique, impulsive convective components obtained separately. Furthermore, effect tank wall flexibility sloshing water free surface accounted for in analysis. complexities associated with modeling conical shaped discussed. This shows that proposed capable accounting fluid-structure interaction liquid containing structures. method, effects complex geometries such as made possible. results show practice predicts reasonable accuracy.
