| Abstract |
This study aims to analyze the typology and historical changes of Daegong(臺工) and Dongjajoo(童子柱) from a functionalist perspective.
Daegong and Dongjajoo are structural members retaining vertical load in traditional Korean roof frame structures. These two structural
members are mostly defined by their locations; Daegong is considered as a vertical member under top-purlin, whereas Dongjajoo is used
under mid-purlins. While they have similarities as vertical load bearing members, there are subtle distinctions in their functions. The structural
roles and components of these members were analyzed by reviewing historical documents and case studies of 194 Daegongs and 203
Dongjajoos from 184 buildings. The structural members with those of similar functions from traditional Chinese and Japanese architecture
were compared. As a result, this study revealed that the function and composition of these two members had changed over time, and such
changes reflect the characteristics of roof frame structures in traditional Korean architecture. |
