Investigation of Traditional Wooden Buildings of Chinese Dong Race

中国东部有一个栋族，他们有许多传统的木结构建筑，如水塔、桥梁、大门、田野舞台等。它们是由柱和梁、Nuki结构建造的，但没有楔子。梁穿过立柱，在柱节点中连接和加劲，没有钉子、钢连接件和楔子，研究的目的是弄清木结构的施工方法和结构力学。我们在侗族村寨进行了大量的田野调查，明确了下一步的工作重点。Dram-Tower主框架施工体系和屋面施工体系。木桥施工体系3。正门和赛场舞台施工体系4。木结构建筑加工5.竹尺原理我们制作了最古老的塔楼和两座大木桥的比例尺模型，验证了我们关于这些结构的结构力学观点的正确性。

There is Dong race in east China who had many traditional wooden buildings such as dram towers, bridges, gates, field stages, and so on. They are constructed with columns and beam, Nuki structures, but they do not have wedges. The beams penetrate the columns, and they are connected and stiffened in the column joint without nails, steel connectors and wedges.The purpose of our investigation is to make clear the construction method and structural mechanics of the wooden structures. We put into force of many field works in Dong race villages.As the result, we made clear the next important items1. Construction system of Dram-Tower main frame and roof construction system2. Construction system of wooden bridge3. Construction system of main gate and field stage4. Processing of wooden architectures5. Principle of bamboo rulerWe made scale models of the oldest dram tower and two big wooden bridges, and we verified rightness of our views about the structural mechanics oh these structures.
