阻尼器系数对悬挂建筑结构减震效率影响研究

利用拉格朗日方程建立了核筒悬挂建筑结构体系运动方程，采用Longe-Kuta方法求解体系地震动力响应时程。实例计算结果表明，阻尼器系数对悬挂结构的减震效果具有明显影响，楼层位移沿结构高度的分布趋于均匀，且相对于普通无悬挂结构其层间位移、层位移、层速度以及层加速度大幅度减小，而且存在一个优化的阻尼器系数使得结构层间位移有最小值。

A Research on the Damping Effect of Damper Coefficients on Suspension Structures

The motion equation for the core tube suspension building structure is established though Lagrange equation, and the response interval of seismic force of the system obtained with Longe Kuta method. The calculation results show that the damping coefficient of the damper has an obvious influence on the damping effect of the suspension structure, that the floor displacement tends to be uniform along the height of the structure, and the inter-story displacement, floor displacement, displacement velocity and acceleration are greatly reduced compared with the ordinary none-suspension structure, and that there exists an optimal damper coefficient which minimizes structure displacement.
