중국목조건축의 두공을 형성하는 부재의 변천과정에 관한 연구

Up to now the study of traditional wooden buildings has been largely concentrated on the configurational aspect of the wooden members. While the actual process of change of the Bracket Members such as doo(point, ), gong (arm, ) and ang(lever~arm, ) which forms doogong (or bracket set, ) are usually neglected. This study, therefore, intends to investigate the process of change of doogong members which plays the key role in classifying the styles of timber-framed architecture of East Asia. The was focused on Chinese traditional architecture.The findings of this study are like followings:Doogong can be classified in three stages according to its pattern of change.1) In the first stage, the shape of chulgong is chumcha type and a point (doo) which bears the weight of the roof actually functions as a structural member supporting other members above it.2) In the second stage, the shape of chulgong is mixed with chumcha, soesch and angseo, and doo tend to its lose role as a point. Gong, alone, supports the weight directly.3) In the third stage, doo loses its structural function completely and the shape of chulgongs projected outside of the buildings are soesuh or angseo type.These 3 stages had been appeared in sequence, and the role of doogongs, were changed from structural function to decorative function. These pattern of changes can be found in China.
