The World’s Oldest & Tallest Surviving Wooden Pagoda
The pagoda was built in 1056 during the North Song Dynasty, measuring 67 metres tall and 30 metres in diameter, supported by a double-layered timber-frame structure, with 24 columns in the external supporting system and 8 columns forming the internal network. Both frames are further reinforced by timber bracings, beams, and short columns.
Such structure has helped the pagoda to survive a dozen major earthquakes in a thousand years, with 3 measuring more than 6 on the Richter scale.
Dougong is the essential part of classic Chinese timber-framed structure that uses interlocked wooden brackets rested on columns to support deep eaves and huge roof, while the walls in traditional Chinese buildings are commonly not load-bearing.
Dougong system has been widely used in traditional Chinese architecture since the Spring and Autumn period (770–476 BC). The highly developed Chinese carpentry craft with precision and quality since the time of Lu Ban allows the timber parts to be fitted together by joinery alone without glue or fasteners.

Without glue or nails, yet it can withstand an earthquake because of its ability to flex and shift while under great stresses.
I really do think it’s the clever construction free from being solid in joints that allow for movement in a major quake. We could learn a lot from these ancient craftsmen.

This is certainly one of the major advantages of the nailless dougong system, coupled with freestanding columns.

This is truly representative of my view of Asian buildings, so different from the evolution of western buildings yet with many similarities. The Asian world has a distinct aesthetic.
All Things Chinese
The pagoda is 1,000-year-old, but I suspect the terrace houses on both sides are pretty new – the traditional Chinese street front houses with mixed commercial and residential usage wouldn’t have big dougong (brackets) like that.
