摘要

为了将颗粒阻尼技术引入到桥梁减震控制领域,提出了一种适合桥梁结构使用的调频型颗粒阻尼器及其设计方法,并以某高架连续梁桥为原型,设计制作了1:10缩尺模型,利用振动台台阵系统对未设置和设置调频型颗粒阻尼器的模型桥进行了振动台试验研究。研究结果表明:调频型颗粒阻尼器的初步设计方法可以为颗粒阻尼技术在桥梁减震领域的应用提供一定的理论指导;调频型颗粒阻尼器在高架连续梁桥减震领域应用效果良好,激励强度是影响阻尼器减震控制效果的主要因素之一;与调谐型阻尼器相比,调频型颗粒阻尼器的减震频带更宽。

Abstract

To study the adaptability of particle damping technology in the seismic control of bridges, a preliminary design principle of tuned particle damper for continuous viaducts has been presented. A 1/10-scale model bridge based on a continuous viaduct has been designed. The shaking table tests on the model bridge with and without dampers have been conducted using the shaking table array system. The research results show the preliminary design method of the tuned particle damper can provide valuable references for the application of particle damping in bridges’ seismic control; Good prospect on the application of tuned particle damper in the seismic control of bridges can be expected according to the research. The tuned particle damper can effectively reduce the seismic response of continuous viaducts while the excitation intensity is one of the keys to the performance of damper. To compare with the Tuned Mass Damper and Tuned Liquid Damper, the Tuned Particle Damper has a more wide control frequency band.
