| 摘 要： | 提出一种新型的耗能稳定的墙式组合型金属阻尼器,能够提供充足的开放空间与开口需求,提高建筑结构抗震能力的同时增加了建筑物使用舒适度。文中利用通用有限元软件ANSYS研究了其在不同位移幅值下的力学性能,探讨了阻尼器初始刚度与铅块金属厚度的关系,并结合工程实例分析论述了该类型阻尼器的耗能减震效果。非线性时程分析结果表明,该阻尼器小震下可提供较大附加刚度和阻尼,有效减小结构的水平变形的同时改善了结构在地震作用下的内力,大震下滞回曲线饱满,耗能稳定,有效地保护了结构构件。

| Abstract: | In the paper,a novel wall-type combined metal damper is presented.The mechanical properties of the hysteretic dampers are studied on the basis of finite element analysis,and the effect of the new type damper in reducing earthquake response and the relation between K and h are discussed.The results of non-linear time-history analysis demonstrate that the structure stress is improved because of added stiffness and damping and the hysteresis loop is full and stable,and the the protection structure successfully plays its role. |
