［摘要］以翁丁古村落干栏式建筑木结构为对象，采用相同材料、相同工艺，制作了三种不同类型1:1梁柱十字节点试件，通过低周反复加载试验获取荷载位移滞回曲线、骨架曲线，分析其承载力、转动刚度、阻尼比等参数，探究节点在不同加载等级下的损伤及阻尼耗能变化规律，进而评估三种节点在地震作用下的力学性能，为下一步对该古村落民居进行性能提升、保护提供重要的参考和依据。［关键词］干栏式木结构; 低周反复加载试验; 滞回曲线; 阻尼; 抗震性能中图分类号：TU366.2 文献标识码：A 文章编号：1002-848X(2016)03-0039-05
Experimental investigation on joint seismic performance of the stilted wooden structures in Wengding ancient villageLai Zhengcong1, Chu Qingqing2, Bai Yu1, Liu Zhanzhong2, Feng Yun2(1 School of Civil Engineering, Kunming University of Science and Technology, Kunming 650500, China; 2 Kunming Architectural Design and Research Institute Co., Ltd., Kunming 650228, China）Abstract:Three types of beam-column cross joint specimens were made with the same material and constructing method as those applied in the stilted wooden structures in ancient Wengding village. The cyclic loading tests were carried out, and loaddisplacement hysteresis curves as well with skeleton curves were obtained, based on which the parameters of bearing capacity, rotating rigidity and the damping ratio were analyzed. The damages and the damping changing laws of the joints under different loading levels were studied, and the mechanical performances of three types of beam-column joints under the earthquakes were evaluated. These research results can provide important reference and basis for promoting and protecting the residential in this ancient village.Keywords:stilted wooden structure; cyclic loading test; hysteresis curve; damping; seismic performance
