［摘要］為研究云南翁丁古村落佤族干欄式木結(jié)構(gòu)民居的抗震性能，選取較為典型的一棟建筑，制作原尺寸模型進(jìn)行振動(dòng)臺(tái)試驗(yàn)。通過試驗(yàn)探討干欄式木結(jié)構(gòu)民居的動(dòng)力特性和抗震性能。試驗(yàn)按當(dāng)?shù)乜拐鹪O(shè)防烈度8度（0.3g）考慮，選擇三條地震波分別進(jìn)行8度多遇烈度、8度設(shè)防烈度和8度罕遇烈度地震作用下的試驗(yàn)，對結(jié)構(gòu)反應(yīng)進(jìn)行分析。試驗(yàn)結(jié)果表明：在設(shè)防烈度為8度（0.3g）的情況下結(jié)構(gòu)只出現(xiàn)局部構(gòu)件輕微破壞，結(jié)構(gòu)整體基本處于彈性，能夠滿足抗震設(shè)防目標(biāo)。研究結(jié)果為該類民居的抗震設(shè)計(jì)提供了依據(jù)。［關(guān)鍵詞］古村落民居; 干欄式木結(jié)構(gòu); 振動(dòng)臺(tái)試驗(yàn); 抗震性能中圖分類號：TU366.2 文獻(xiàn)標(biāo)識碼：A 文章編號：1002-848X(2015)14-0008-05
Shaking table test study on Wa nationality stilted wood structure dwellingsChu Qingqing1, Bai Yu2, Feng Yun1, Liu Zhanzhong1, Lai Zhengcong2（1 Kunming Architectural Design and Research Institute Co., Ltd., Kunming 650228, China; 2 School of Civil Engineering, Kunming University of Science and Technology, Kunming 650500, China）Abstract: To evaluate the seismic performance of Wa nationality stilted wood structure dwellings in Yunnan Wengding ancient village, a full size typical house was subjected to a shaking table test. The dynamic characteristics and seismic performance of the stilted wood structure dwelling were analyzed in the test. Three earthquake waves were chosen for 8-degree frequently occurred earthquake, 8-degree design earthquake and 8-degree rarely occurred earthquake according to the local seismic fortification intensity of 8-degree (0.3g). Experimental results show that this structure only has slight damage component in the fortification intensity of 8 degrees (0.3g), the whole structure is basic in elastic and can satisfy the seismic fortification goal. The results provide anti-seismic basis for design of this kind of local dwelling.Keywords: ancient village dwelling; stilted wood structure; shaking table test; seismic performance
