What did Dougong Bracket Set look like?

Multiple sets of dou (bearing blocks) and gong (cantilever curved timbers) are stacked layer upon layer, cantilevering outward to form a conical load-transfer system. The assembly combinations are extremely complex.

How did Dougong Bracket Set work?

Roof weight → purlins → dougong layers → load is decomposed layer by layer → vertical component transmitted to columns → horizontal component linked across columns via tie beams → during earthquakes, mortise-and-tenon joints in each dougong layer undergo micro-movement → friction dissipates energy → reduces structural vibration.

Dougong Bracket Set

A tiered cantilever timber load-transfer system that decomposes the enormous roof load layer by layer and transmits it to the columns, while also buffering seismic forces through mortise-and-tenon micro-movement.

Scientific Principle

Cantilever structure: moment equilibrium of tiered cantilevers. Force flow transmission: vertical dispersion + horizontal series connection. Frictional energy dissipation for seismic damping.
