摘要:
In order to clear the influence of the layout scheme of particle dampers on its control effect for building structures, a 1/30-scale reinforced concrete frame model was taken as a research object, a kind of particle dampers connected to the scaled model rigidly to reduce the vibration of the model was designed and manufactured, the layout scheme of particle dampers was designed according to the shock absorption requirement of the tested model, and the influence of the layout position and the number of dampers on the control effect was analyzed through a series of shaking table tests. The results show that the root mean square displacement response and peak displacement response of the structure where there is a particle damper are both decreased, and the particle damper designed has a good control effect. The layout position of particle dampers has significant impact on the control effect, particle dampers should be placed on the place where the displacement response is larger, and a reasonable layout scheme of particle dampers can effectively reduce the torsion response of the structure. The vibration control effect on the displacement response increases with the number of particle dampers increasing. In other words, in the available additional mass ratio range for building structures, the control effect increases with the additional mass ratio increasing. © 2020, Editorial Office of Journal of Vibration and Shock.
