Interlocking bracket sets are formed by placing a large wooden block (dou) on a column to provide a solid base for the bow-shaped brackets (gong) that support the beam or another gong above it. Adding multiple sets of interlocking brackets or dougong reduces the amount of strain on the horizontal beams when transferring their weight to a column. Multiple dougong also allows structures to be elastic and to withstand damage from earthquakes. More than supporting the roof, dougong was later developed into a decorative ornament for buildings with beautiful appearance and various types. There are over sixty types of dougong in the wooden pagoda in Yingxian which is the tallest timber structure building.

As Chinese wood structures have such a good quake-proof design, why not turn to them for inspiration when new buildings are constructed in quake-prone areas?
