结构变刚度/变阻尼控制若干问题的研究

Study on Key Problems in Semiactive Structural Control by Using AVS and AVD

尽管已有的研究证明,传统的半主动变刚度控制系统和变阻尼控制系统均可以有效地抑制结构在地震激励下的动力反应,然而最新的研究显示二者仍然存在明显的不足之处,需要进一步深入研究。本文首先就变刚度/变阻尼控制目前的研究现状分别进行了综合论述,然后重点探讨了二者各自存在的不足之处,并指出了值得关注的后续研究方向。

Although it has been demonstrated that as two typical examples of conventional semiactive control systems, active variable stiffness （AVS） and active variable damper （AVD） may be effective for vibration control of buildings subjected to seismic excitations, the latest research results show that obvious deficiencies sti//exist in both of them. In this paper their recent developments are introduced, followed by analysis of their main deficiencies. Meanwhile, the focus of further research is also presented.
