A friction-type tuned mass damper (FTMD) system is adopted in this study as the target for implementing the real-time hybrid testing technique. In the beginning, 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 loadings can be investigated and ensured. Then, the main structure is replaced by its numerical model and is embedded inside the real-time hybrid testing configuration. The total shear force (the equivalent inertial force) calculated from the measured acceleration is fed back into the simulation part to compute the absolute displacement command of the main structure. The shaking table is then adopted as the test bed of the real-time hybrid testing to behave like the main structure and to interact with the equipped FTMD system. The test results of both real-time hybrid tests and their corresponding shaking table tests illustrate similar control performance of the FTMD. Therefore, the real-time hybrid testing technique can be extended to friction-type control devices. |
