［摘要］以翁丁古村落干欄式建筑木結(jié)構(gòu)為對(duì)象，采用相同材料、相同工藝，制作了三種不同類型1:1梁柱十字節(jié)點(diǎn)試件，通過(guò)低周反復(fù)加載試驗(yàn)獲取荷載位移滯回曲線、骨架曲線，分析其承載力、轉(zhuǎn)動(dòng)剛度、阻尼比等參數(shù)，探究節(jié)點(diǎn)在不同加載等級(jí)下的損傷及阻尼耗能變化規(guī)律，進(jìn)而評(píng)估三種節(jié)點(diǎn)在地震作用下的力學(xué)性能，為下一步對(duì)該古村落民居進(jìn)行性能提升、保護(hù)提供重要的參考和依據(jù)。［關(guān)鍵詞］干欄式木結(jié)構(gòu); 低周反復(fù)加載試驗(yàn); 滯回曲線; 阻尼; 抗震性能中圖分類號(hào)：TU366.2 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：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
