摘　　要：本文结合某电信大楼结构实际工程 ,应用电液式变刚度结构振动控制系统 ,对其进行抗震控制的计算和技术经济分析。计算结果表明 :在结构中采用电液式变刚度结构控制系统 ,不仅结构的地震反应得到了有效的控制 。The Electro_hydraulic Variable Stiffness System (EHVSS) is proposed as a structural vibration control system.According to the response,the variable stiffness alters its on/off state in such a way 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 high winds and earthquakes.Based on the above,A 40/50t full_scale EHVSS is successfully manufactued to be used in some buildings and is subjected to performance test.The full_scale EHVSSs have been used in some high_rising biuldings.Analysis results indicate that It is able to save greatly civil engineering investment using EHVSSs in anti_seismic buldings.
