碩士 === 國立成功大學 === 土木工程學系 === 105 === The pseudo dynamic test is a combination of numerical analysis and experimental test that can emulate the dynamic behavior of structure under environmental loading such as seismic event. However, the behavior of the isolator which is depending on velocity or friction is hard to replace by the pseudo dynamic test. The first purpose of this thesis is to evaluate the applicability of real time hybrid test (RTHT) of a piezoelectric friction controllable mass damper system (PFCMD) by comparing its performance with shaking table test. The key interface of RTHT is the feedback inter-story shear force between the PFCMD and the main structure, where the PFCMD is an experimentally physical substructure that directly installed on a shaking table and the main structure is numerically simulated by a shaking table. The result of testing shows that the responses of main structure and PFCMD during RTHT are similar to the shaking table test. Therefore, the design of PFCMD for reuction of seismic vibrations in multiple degree of freedom stuctures are tested through RTHT. The optimization of the control parameters on PFCMD-structure system is also investigated.
