Abstract
The traditional wooden frame structures of Chinese Dong People have passed through the ages. We investigated the details of the construction system of drum towers, bridges, gates, granaries and drama stages in Dong villages, which are constructed with posts and beams. The beams penetrate the columns and are connected and stiffened without using wedges. In addition, nails and steel connectors are not used. The purpose of the investigation is to make clear the construction system of the traditional wooden structures. We deciphered the allotment of timber written on the surface of bamboo, which were very important for marking, processing and construction of the structures.
