用于村镇木结构建筑的新型角位移阻尼器的性能实验研究
|
摘要
该文在分析木结构建筑在地震作用下破坏机理的基础上,提出了适用于村镇木框架结构房屋的新型角位移阻尼器,并对该角位移阻尼器的结构和工作原理进行了介绍。通过力学试验及低周疲劳试验研究,分析了该阻尼器在不同温度、加载频率和控制位移情况下各种性能参数的变化规律,证明这一新型阻尼器具有良好的变形能力、耗能能力和抗疲劳性能。
In this study,a new Angle-displacement Damper suitable for the wood frame buildings in rural areas is designed on the analysis of destroying mechanism of wood frame buildings under earthquakes.Its structure and working principle are also given.The variety laws of several function parameters of this damper in different temperatures,loading frequencies and controlling displacements has been analyzed through mechanical experiments and a low cycle fatigue test.It is proved that this damper has good deformation capacity,energy dissipation and anti-fatigue performance.
