Development of a hybrid vibration experiment system for wind-induced responses of buildings with tuned dampers

Abstract

As the simulation (experiment) technique of a physical phenomenon, there are a numerical computation, a model experiment, and the hybrid technique of both methods. The hybrid technique was proposed by Hakuno(1968), and have been applied in various fields. For wind engineering field it have been applied to the wind tunnel experiment by Kanda(1994). In this study, the hybrid experiment technique is applied to wind affected structures that have complicated vibration damping equipments. Although it is easy to carry out numerical modeling of the tuned mass damper which consists of the simple mass and the spring elements, prediction of the characteristic at the nonlinear nature of fluid to the time of large amplitude and prediction of the action at the time of random vibration are comparatively difficult for the tuned liquid dampers that are applied sloshing of liquid. This study is aiming at development of the hybrid oscillating experiment system for evaluating such dampers.
