Abstract

Rectangular tuned liquid dampers were investigated through shaking table tests and numerical modeling for large amplitude excitation. The results confirm earlier work undertaken for small amplitude excitation and considerably contribute to the body of knowledge describing tank behavior under large amplitude excitation. The random choice method of solving the fully nonlinear shallow-water-wave equations captures the underlying physical phenomenon adequately, including wave breaking, for most of the frequency range of interest. The tank behaves as a hardening spring system due to the liquid sloshing motion, and this trend is enhanced as excitation amplitude increases.
