提出了一种新型消能减震振动控制系统,其构造包含非耗能支撑子系统和消能子系统。非耗能支撑子系统依据机构学领域中的准直线运动机构将两根钢拉杆支撑构件交叉配置,且端部采用铰接形式,因此支撑构件中不产生轴向压力。消能子系统为将两个U型阻尼安装于中间铰接的两块钢板中间,通过U型阻尼的屈服变形吸收地震能量。通过理论分析给出了振动控制系统的刚度和承载力的分析方法,并进行了循环荷载试验,论证了理论分析的精度。
A new energy-saving damping vibration control system is proposed. Its structure includes non-energy-consuming support subsystem and energy-dissipating subsystem. The non-energy-consuming support subsystem is based on the alignment movement mechanism in the field of mechanics to cross the two steel tie rod support members with hinged ends so that axial pressure is not generated in the support members. Energy Dissipation Subsystem To absorb the seismic energy through U-shaped damping yielding deformation, two U-shaped dampers are installed between two hinged steel plates. The analysis method of stiffness and bearing capacity of vibration control system is given through theoretical analysis, and the cyclic loading test is carried out to demonstrate the accuracy of theoretical analysis.
