水平组合结构体系的变刚度控制

Semiactive Structural Control of Adjacent-Buildings Using Variable Stiffness

实际工程中，组合结构体系应用广泛，为此本文对在水平结构组合体系的子结构之间安装可变刚度系统，采用变刚度吸能释能控制律，进行了分析。分析表明，采用这种变刚度半主动控制，能够使组合体系在地震作用下的动力反应得到有效的控制。

The Semiactive Variable Stiffness System(SVSS) has been proposed as a structural vibration control system. According to the response, the variable stiffness alters its on/off state in such a way as to absorb and release the motion energy of the controlled structure. Theoretical analysis and shaking table test show that the SVSS is capable of alleviating efficiently the vibration of structures subjected to both strong winds and earthquakes. This paper proposes the SVSS as a structural vibration control system of adjacent-buildings. Analysis results indicate that the SVSS is capable of alleviating efficiently the vibration of seismic-excited adjacent-buildings.
