STUDY ON THE MECHANISM AND THE EFFECTIVENESS OF ENCLOSURE WALL MULTI-FUNCTIONAL VIBRATION-ABSORPTION STRUCTURES
As a new style of damping structure,enclosure wall multi-functional vibration-absorption structures (EWMVS) integrates the merits of infilled frame,tuned mass control (MTMD) and the energy dissipation structures,therefore EWMVS not only can dissipate energy and absorb the shock actively,but also have obvious economic benefits. The paper studied the mechanism of shock absorption of EMWVS,also analyzed the main factors that influence damping effect such as the mass ratio,the stiffness ratio,the damping ratio,the number and location of the enclosure wall and so on. The results indicate that there are optimal value of the mass ratio,the stiffness ratio and the damping ratio of substructure in EWMVS,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 devices performance parameters as well as necessary optimization of MTMD parameters according to the specific case of actual structurel.
