［摘要］为研究云南翁丁古村落佤族干栏式木结构民居的抗震性能，选取较为典型的一栋建筑，制作原尺寸模型进行振动台试验。通过试验探讨干栏式木结构民居的动力特性和抗震性能。试验按当地抗震设防烈度8度（0.3g）考虑，选择三条地震波分别进行8度多遇烈度、8度设防烈度和8度罕遇烈度地震作用下的试验，对结构反应进行分析。试验结果表明：在设防烈度为8度（0.3g）的情况下结构只出现局部构件轻微破坏，结构整体基本处于弹性，能够满足抗震设防目标。研究结果为该类民居的抗震设计提供了依据。［关键词］古村落民居; 干栏式木结构; 振动台试验; 抗震性能中图分类号：TU366.2 文献标识码：A 文章编号：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
