摘　　要：铅剪切阻尼器是一种耗能性能优越、构造简单而又十分经济的结构减震控制装置.为提高梁柱节点的耗能能力,本文开发了一种具有变形放大功能的转动式铅剪切阻尼器,利用ANSYS软件对该阻尼器进行了数值模拟分析,研究了铅块高度和宽度对其性能的影响;通过低周往复荷载试验,同时,还研究了振幅、频率、荷载循环次数、去掉对该阻尼器性能的影响.结果表明,这种新型转动式铅剪切阻尼器滞回曲线饱满、性能稳定.A new-type compact rotational lead shear damper was developed as a supplementary damping for beam-column joints in structures in this paper. Numerical analyses of the damper were carried out to study the influencing factors including the width, height of lead and amplitude, frequency, cycling of loading. The research results indicate that the rotational lead shear damper is characterized by plump hysteresis loops and steady performance, and it will he an excellent energy dissipation device.
