运用最近提出的阻尼筒控制系统对高层建筑结构扭转耦合地震反应阻尼器控制进行振动台模型试验研究。首先简要介绍了阻尼筒控制系统的构造和控制原理及其阻尼特性的测试试验,继而在振动台上对一三层钢框架模型进行了模型试验研究。试验结果表明,通过对该三层框架模型施加阻尼筒控制,其顶层扭转角位移反应得到了显著的降低,从而验证了阻尼筒控制系统不仅能有效地控制高层建筑结构的水平地震反应,而且能有效地控制高层建筑结构的扭转耦合地震反应,因而在工程中具有广阔的应用前景。
Using the recently proposed damping cylinder control system, a shaking table model test study was conducted on the torsional-coupling earthquake response damper control of high-rise building structures. Firstly, the structure and control principle of the damping cylinder control system and the test of its damping characteristics are briefly introduced. Then a three-layer steel frame model is model-tested on the vibration table. The experimental results show that by applying the damping cylinder control to the three-story frame model, the top-level torsional angular displacement response is significantly reduced, thus verifying that the damping cylinder control system not only can effectively control the horizontal seismic response of high-rise building structures, but also Effectively control the torsional coupled seismic response of high-rise building structures, and thus has a broad application prospect in the project.
