Description
Technical Field

Background
The straight tenon is a common node form in the wooden structure of the historic building. The straight tenon joint consumes energy generated in earthquake through mutual friction and slippage among the components, thereby playing the role of energy dissipation and shock absorption. The performance of the straight tenon joint has important influence on the seismic performance of the whole wood building structure.
In the straight tenon-and-mortise joint, the wood beam directly penetrates through the wood column, so that the section of the column is greatly weakened.
