本文通过粘性阻尼墙的非线性动力学试验建立阻尼参数力学模型,研究阻尼参数在具有横向干扰运动剪切模式的非线性特性及随振动幅值和振动频率的变化规律,给出适合工程应用的参考经验的拟合公式。研究显示粘性阻尼墙在剪切模式下可提供高层建筑较大的阻尼特性,横向干扰运动对阻尼常数有一定的影响,研究结果可以为工程应用提供参考,可为高层建筑抵制地震和风振提供有效的动力学设计手段。
In this paper, the dynamic model of viscous damping wall is used to establish the mechanical model of damping parameters, and the nonlinear characteristics of damping parameters with transverse disturbance and the variation with vibration amplitude and vibration frequency are studied. Reference empirical fitting formula. The results show that viscous damping wall can provide larger damping in high-rise buildings in shear mode and lateral disturbance movement has certain influence on damping constant. The results can provide reference for engineering application and provide effective solutions to high-rise buildings against earthquakes and wind vibration Kinetic design tools.
