The aim of this study is to clarify the representation method based on construction and design on large span buildings by contemporary Japanese architects. Firstly, the characteristic of segmentation in structure is analyzed by the relationship between structural components and roof shapes. Secondly, the characteristic of segmentation in ceiling surfaces are analyzed by the relationship between types of ceiling materials and positions of ceiling surfaces. Finally, 12 types of segmentation are determined through the combination between previous two characteristics. It is pointed out that large span buildings have three spaces which have the relation between a central part and peripheral parts by segmentation in both structure and ceiling surfaces.
