摘要
可变刚度系统应用于单体结构能够取得显著的振动控制效果。本文提出了组合结构体系的变刚度半主动结构振动控制，并通过对水平两自由度组合结构体系的变刚度吸能释能控制系统的研究，揭示了水平组合结构体系变刚度振动控制的机理。分析表明，采用这种变刚度半主动控制，能够使组合结构体系在地震作用下的动力反应得到有效的控制。
The Semiative Variable Stickness System (SVSS) has been proposed as a strUctUralvibration control syStem. The variable Stickness alters its state according as the controlledsmictUre absorbs or releases the motion energy. This paper proposes the SVSS as a smictUralvibration control system of adjacent-buildings. The general equation of the SVSS is established.Analytical simulation of controlled systems with tWo degrees of freedom is made. AnalyticalresultS indicate that the SVSS is capable of alleviating efficiently the vibration of seismic-excitedadjacent-buildings.
