Abstract
Enclosure wall multi-functional vibration-absorption structures (MVEW) is a new style of damping structure, it integrates the merits of infilled frame, tuned mass control (MTMD) and the energy dissipation structures. The main influence factors of MVEW is analyzed in the paper, The results indicate that there are optimal value of the mass ratio, the stiffness ratio and the damping ratio of substructure in MVEW, and the damping effect become obvious as the increase of the number of substructure, it also shows that the best location ought to synthetically consider the number of substructure, the tuned frequency ratio and control mode instead of being fixed. In the end, the paper proposed the determine principle of the damping device’s performance parameters as well as necessary optimization of MTMD parameters according to the specific case of actual structure1.
