EXAMINATION OF WOODEN GEODESIC DOME USING JAPANESE STEREOTOMY

Abstract

In case that a geodesic dome is constructed using wooden panels, the frame section of each panel becomes a parallelogram. Therefore, when constructing frames, it is necessary to obtain angles of the member section and cutting angles of the edge. We attempted to determine these angles by an illustration method using Japanese stereotomy traditionally used by carpenters in Japan. We examined an alternate 2v-type geodesic dome and consequently established the correspondence between results of geometric calculations and those of the illustration method. Further, a prototype dome was built on the basis of these results.
