There are a lot of methods can improve the ability of a structure to resist earthquakes effectively. Among them, the structural control technology has been rewarded as the best way for seismic mitigation. The theoretical study, shaking table test and real earthquake experience has proven that the structural control technology can improve the earthquake resistibility and endure safety of a structure.
In recent ten years, the base isolation technology has been robust for applications to buildings. The life of people has been relying on modern science and technology. Therefore, people will face not only the direct impact of building damage by earthquake but also indirect impact of damage of non-structural components such as the ancient object inside the museum and semiconductor and microelectronics in the electronic factory. Their impact caused damage in the high-Tech industry may be more serious than that from the building itself. Therefore, the application of the base isolation should not be building in the range of base isolation now. Technology should be extended to ensure the safety of the cultural relics and historic sites and sensitive equipment.
Thus, in order to offer an isolator which is economical and effective for motion sensitive equipment, this study proposes a Trench Friction Pendulum System（TFPS）to motion sensitive equipment. First, we would like to investigate its characteristics and advantages, to derive mathematical for mutations for theoretical study and to perform shaking table tests to examine its efficiency in seismic mitigation for motion sensitive equipment. When subjected to the 1940 EL Centro, 1995 Kobe and 1999 Chi-Chi earthquakes, the test result has proven that the Trench Friction Pendulum System can reduce the response of the motion sensitive equipment during earthquakes.
