摘要

粘滞阻尼墙是近年研制的新型粘滞阻尼装置。本文通过水平快速周期性加载试验,对粘滞阻尼墙的动力性能进行了全面研究,探讨了环境温度、位移幅值及加载频率对粘滞阻尼墙动力性能的影响规律,推导出粘滞阻尼墙阻尼力与加载速度间的相关关系,并提出了粘滞阻尼墙阻尼力的理论计算公式。研究表明,新型粘滞阻尼墙的动力性能受环境温度、位移幅值、加载频率的影响较大,本文提出的阻尼力理论计算公式可靠,可应用于工程实际。
Viscous damping wall is a type of newly developed dampers.Dynamic experiments on VDW under different temperatures,frequencies,and displacements have been performed.The relationship of dynamic performance to environmental temperature,displacement range,and the loading frequency are discussed in the paper.The theoretical formulation about the calculation of the viscous damping force is also proposed.The experiment results show the VDW has good energy-dissipating ability,and the formulation suggested is practical for use.
