Final answer:
The bracket sets on Chinese buildings are known as Dougong, a distinctive feature in Chinese architecture essential for supporting the roof and creating overhanging eaves.
Step-by-step explanation:
The bracket sets on Chinese buildings are called Dougong. Dougong is a unique structural element of interlocking wooden brackets that are significant components in traditional Chinese architecture. The use of these special brackets dates back to the Spring and Autumn period (770–476 BC), and they became more complex and ornate during the subsequent dynasties. Dougong consists of a series of interlocking parts that send the downward force of the roof through the column, allowing for the creation of overhanging eaves and sweeping rooflines characteristic of Chinese buildings.
The intricate nature of Dougong involves multiple bracket sets that are carved and inserted into other carved interlocking pieces. This not only allows for the support of the roof but also provides a method for the construction of multiple stacked brackets, adding both strength and aesthetic value to the building. It is a testament to the skill and ingenuity of ancient Chinese architects and carpenters.
