Summary: | 碩士 === 國立中興大學 === 土木工程學系所 === 101 === A multiple TMD (MTMD) consists of multiple units of tuned mass dampers (TMDs) arranged in parallel to deal with one single structural mode. By attaching MTMD to a structure, vibration energy of the structure can be transferred to the MTMD and dissipated via the damping mechanism. Compared with the single TMD, the MTMD performs better and is able to avoid detuning effect. However, it is generally understood that the existing TMDs in the high-rise buildings in Taiwan, their design and manufacture all relied on foreign consultants and techniques. The main reason is lacking of the experience in designing and manufacturing a full scale TMD. According to these reasons, an automatic optimal MTMD design program is firstly developed based on the MTMD theory. Then, the manufacture procedure of the MTMD components and practical considerations to implement in a real building are developed. Finally, a scale-down long period MTMD system is manufactured and tested via a shaking table. Test test result is agree with the theoretical model. This study shows the domestic technology does have the ability to design and manufacture the MTMD system for the vibration reduction of high-rise buildings.
