建筑结构半主动控制振动台试验研究

本文讨论了作者进行的建筑结构半主动振动控制试验,用以检验主动变刚度/阻尼(AVS/D)控制系统犤6犦及瞬时最优半主动控制方法的有效性与实用性。试验结果表明:对比于对应的被动控制方式,AVS/D半主动控制系统不但能有效地控制结构在地震作用下的位移和加速度响应,而且克服了其它半主动控制系统存在的负面控制影响,对不同地震激励具有很强的控制鲁棒性,而且实现简单、易行,从而为进一步深入研究与应用于工程实际提供了试验依据。

Shaking-table Test on Structural Semi-active Control

The shaking-table test on semi-active control of structural engineerin g conducted by authors is discussed i n this paper to demonstrate the performance and effectiveness of the activ e variable stiffness /damper(AVS /D)system and the corresponding instantaneou s optimal semi-active control method.The experimental results indicate that the AVS /D semi-active control system an d the control method presented in thi s paper can not only control effectiv ely the structural displacement and accele ration response under earthquake action in contrast with the cases of no c ontrol and passive control respectively,but also avoid the negative influence induced by the traditional semi-active control systems.Moreover,it performs robust under different earthquake excitation,an d can be realized easily.So it lays an experimental foundation for further research and engineering practice.
