Seismic Performance Analysis of the Elevated RC Tanks under Strong Far- and Near-Fault Ground Motions Considering Fluid–Structure Interaction

The elevated reinforced concrete tanks assessed in the current work were subject of a nonlinear sloshing analysis resulting from fluid–container interactions. primary response quantity interest was height free surface sloshing. To achieve this aim, effect liquid contents on seismic behavior subjected to various sets far- and near-fault ground motions measured. variables considered study included bidirectional loading, earthquake’s frequency content, water sloshing, three-dimensional geometry. goal analyze these crucial parameters through parametric using finite element method considering influence fluid–structure interactions under different motions. By contrasting numerical results obtained by previous studies those investigation, applicability simulation analyses then examined, significant conclusions formed. findings showed that nonlinearity may significantly affect performance liquid–container failing properly account for it pose severe threat structures’ ability perform satisfactorily particular class tanks, particularly events.
