N2 - Conical shaped vessels are widely used as water containment in North America as well as in various places around the world. However, the current standards for the design of water structures, which are usually based on the specifications provided by the American Water Work Association, do not provide a direct seismic design procedure for such structures. This paper includes the first experimental investigation for the dynamic behavior of liquid-filled conical tanks. In this experimental program, a scale model is used to simulate typical steel prototype dimensions. The model, which is made of aluminum, is mounted to a shake table device and subjected to lateral excitation. The dynamic response of the empty as well as the water-filled model is assessed by applying white noise and harmonic excitations at the table level. The liquid sloshing mode as well as the coupled liquid-shell sloshing and impulsive modes are evaluated. The results indicated the significant influence of the geometric imperfections on the dynamic behavior of the tanks. In addition, the results validated the common assumption of de-coupling between the shell vibrations and the liquid sloshing mode.
