摘要

为了满足三维隔震装置对阻尼的需要,设计了一种新型的异型铅阻尼器。该阻尼器的最大特点,是能够同时提供水平和竖向阻尼。通过水平剪切和竖向拉压试验,研究了异型铅阻尼器在不同振幅、不同频率组合下的力学性能。试验研究表明,异型铅阻尼器水平向和竖向的滞回曲线比较丰满、耗能效率高、工作性能稳定,可以作为建筑及桥梁结构风振和抗震控制的消能装置。
A new type deformed lead damper is designed to meet the three-dimensional isolated equipment's requirement of damping,the most characteristic of the damper is that it can provides with horizontal and vertical damping simultaneously.In order to analyze the basic mechanical behaviors of deformed lead damper,a series of tests are made.The study of tests show that the horizontal and vertical hysteretic curve are chubby,the efficiency of energy dissipation is high,and the performance is stable.The deformed lead damper is suitable for vibration control of building and bridge structures.
