COLUMNS TO TAKE THE LOAD
Axial Bracket Arm As an important component in the building, the bucket arch connects the preceding and the following, and plays the role of transferring load. The mechanical prototype of the bucket arch is a short cantilever beam, and the overall stability is achieved by increasing the beam height layer by layer.

Many bucket arches have oblique fractal bifurcations from the support to the load end, which are similar to the structural prototypes of tree-shaped columns and natural tree branch fractals. In the original scrolling position of the bucket arch, a large number of materials have been deleted.

COMPARISION OF OLD AND NEW SECTIONS OF THE MAIN HALL Left is traditional wooden architecture Right is structure topology result
The structural topology optimization was carried out for the brackets, columns, transverse beams, diagonal braces and forks in the building, and only the ground and wooden structure were retained in the renderings.
