Bucket arch, a wood structure
Why does bucket arch play a very important role in ancient Chinese architecture?
It is located between the column and the beam. The load transmitted from the roof and the upper structure is transmitted to the column through the
bucket arch and then from the column to the foundation. Therefore, it plays the role of connecting the upper and lower and transmitting the load.
It extends outwards, allowing the outermost layer of sandalwood to extend a certain distance, making the building more far-reaching and more
beautiful and spectacular.
It is exquisitely constructed and beautifully shaped. It looks like a bonsai or a flower basket and can be a good decorative component.
The combination of mortise and tenon is the key to earthquake resistance. This structure is very similar to the modern beam-column frame structure. The nodes of the frame are not just connected, which ensures the stiffness coordination of the building. In the event of a strong earthquake, the
spatial structure combined with mortise and tenon will be “loose” but not “scattered”. It can consume the energy from the earthquake, greatly
reducing the seismic load of the entire house and resisting the earthquake.
