Abstract

This paper is a typological analysis of the correlation between the framing system and the spatial composition in Japanese traditional timber houses. Focussing on the adjoining system between core and outer structure, the transfer routes of roof load are classified by criteria: inside or border of room, inside or border of main frame. Analyzing the arrangement of columns supporting the roof frame, three types of supporting system are characterized, such as column supporting, torii supporting, and girder supporting. Considering the tendency to omit columns inside rooms and coexistence of various types of transfer routes, a series of development stage of framing systems are clarified.
