碩士 === 國立成功大學 === 土木工程學系 === 102 === The friction-type tuned mass damper system (FTMD) is adopted in this thesis as the target for implementing the hybrid testing technique. Firstly, the shaking table tests of the FTMD controlled by high/low friction setups are conducted. The vibration suppression of the main structure equipped with the FTMD subjected to earthquake loading can be investigated and ensured. Secondly, the main structure is replaced by its numerical model and is embedded inside the hybrid testing configuration. The total shear force estimated from the inertial force calculated from the measured acceleration is fed back into the simulation part to find the absolute displacement command of the main structure. The shaking table is then adopted as the test bed of the hybrid testing to behave like the main structure and to interact with the equipped FTMD system. The test results of both hybrid tests and their corresponding shaking table tests illustrate similar control performance of the FTMD. Therefore, the hybrid testing technique can be extended to the friction-type control devices
