Traditional wooden structures

The traditional Chinese wood structure building is a frame structure formed by large wood components such as columns, beams, purlins, braces, and arch of wooden architecture to bear the loads from roofs and floors, as well as wind and seismic forces. At the latest in the 2nd century BC, the Han Dynasty formed two main forms of wooden structural systems, represented by the lifting beam style and the penetrating bucket style. The key technology of this wooden structure system is the mortise and tenon structure, which means that the connection between wooden components does not require auxiliary connection components made of other materials, mainly relying on the insertion between two wooden components.
