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。
Based on the analysis of the failure mechanism of wood-framed buildings under the action of earthquake, this paper proposes a new type of angular-displacement damper suitable for village-town wooden frame houses, and introduces the structure and working principle of the angularly-damped damper. Through the mechanical test and low-cycle fatigue test, the changing law of various performance parameters of the damper under different temperature, loading frequency and control displacement is analyzed. It is proved that the new damper has good deformation capacity, energy dissipation capacity and Anti-fatigue performance.
