Abstract
This paper presents the experimental simulation on a prototype of a typical suspended water tank. The experimental results have been compared with numerical simulations by adopting two different models for the evaluation of the dynamic sloshing effects in presence of the seismic actions. The first one is a concentrated mass model, analyzed by the numerical code SAP2000 and the second one is a continuous model analyzed by the numerical code FemLab. The results of the experimental analysis allowed the validation of the numerical modeling and showed the importance to evaluate the dynamic sloshing effects in the design and in the seismic verification of a water tank in seismic areas. The experimental investigation confirms the reliability of the numerical models proposed, by highlighting the validity of the simplified model with concentrated masses for the evaluation of the shear force and the bending moment at the base of the tank. More sophisticated numerical modeling are needed only for the evaluating the stress/strain states generated in the walls of the water tank.
