摘要：
A modularized suspended floors system (MSFS) was proposed based on the principle of building modularity and vibration controlling by using suspended floors. A distributed array multiple tuned mass dampers (d-array-MTMDs) system was constructed using floor stabs as the masses of TMDs. Thirty-two ground motion records were impat for time-history analysis and the optimal values of the five parameters were given, including the average tuning frequency ratio r), the tuning bandwidth coefficient f3, the tuning damping ratio £T, the number of TMDs n, and the number of layers N of the main structure. The results show that the damping effect of the d-array-MTMDs system is better than that of the ordinary MTMDs system. £T has little influence on the vibration control performance of the system. When r is 0. 7 - 1.0 and f3 is 2.0, the system has the best vibration control effect. When n is greater than a certain threshold, the vibration control effect and stability of the system are improved significantly. The threshold is positively correlated with r and negatively correlated with £T. With the increase of the storey number of a module building, the system can still maintain an improved vibration control effect. © 2024 Chinese Vibration Engineering Society. All rights reserved.
