| Abstract: | In this research project, the vibration mitigation performance of a multiple pendulum tuned mass damper (MTMD) system is evaluated and compared to the vibration mitigation performance of a single pendulum tuned mass damper (TMD) system. Two steel truss models of the Taipei 101 building are constructed, including the TMD and MTMD systems, using the finite element method (FEM). The dynamic behaviour of both systems is compared through numerical analysis based on suppression ability, robustness, space usage and off-tuning mitigation. The systems are assessed for various fundamental natural frequencies of the building in the models to simulate the short- and long-term off-tuning of the building frequency. It is found that the single TMD system which is currently installed in the Taipei 101 building performs more efficiently than the proposed MTMD system, based on the mentioned comparison methods. The difference by which the single TMD system outperforms the MTMD system is small for both the correctly tuned and the off-tuned fundamental natural frequencies of the building, although the suppression ability of both systems equally improves when the systems are tuned to the correct frequency. However, since the single TMD system requires less space and less materials, the single TMD system is more appropriate than the proposed MTMD system. The results provide insight in the behaviour of TMD and MTMD systems in general and are relevant for further comparison studies between these systems, for implementation in wind-excited structures. |
