Carpenters of Japanese Ancestry in Hawaii Hisao Goto Kazuko
Craft History and the Merging of Tool Traditions: Carpenters of Japanese Ancestry in Hawaii Hisao Goto Kazuko Sinoto Alexander Spoehr For centuries the Japanese have made extensive use of wood as the main raw material in the construction of houses and their furnishings, temples, shrines, and fishing boats. As a wood-worker, the carpenter is one of the most ancient of Japanese specialists. He developed a complex set of skills, a formidable body of technical knowledge, and a strong tradition of craftsmanship to be seen and appreciated in the historic wood structures of contemporary Japan.1 The first objective of this study of carpenters of Japanese ancestry in Hawaii is to throw light on how the ancient Japanese craft of carpentry was transplanted from Japan to a new social, cultural, and economic environment in Hawaii through the immigration of Japanese craftsmen and the subsequent training of their successors born in Hawaii. Despite its importance for the understanding of economic growth and develop- ment, the craft history of Hawaii has not received the attention it deserves. The second objective of the study is more anthropological in nature and is an attempt to analyze how two distinct manual tool traditions, Japanese and Western, met and merged in Hawaii to form a new composite tool tradition. This aspect of the study falls in a larger field dealing with the history of technology and of tool traditions in general. Carpentry today, both in Japan and in the United States, relies heavily on power rather than hand tools. Also, carpenters tend to be specialized, and construction is to a major degree a matter of assembling prefabricated parts. -

Platform Frame Construction (Part 2)
STRUCTURAL TIMBER 4 ENGINEERING BULLETIN Timber frame structures – platform frame construction (part 2) Introduction Horizontal diaphragms and bracing In Timber Engineering Bulletin No. 3 (part 1 in this sub-series on platform Horizontal diaphragms in platform frame buildings are provided by the frame construction), the composition and terminology used for platform intermediate floors (with a wood-based subdeck material fixed directly to the timber frame building structures, and the structural engineering checks which joists) and the roof structure (with either a wood-based ‘sarking’ board or are required to verify the adequacy of the vertical load paths and the strength discrete diagonal bracing members) (Figure 3). These horizontal structural and stiff ness of the individual framing members, was introduced. diaphragms transfer horizontal loads acting on the building to the foundations by means of their connections to the wall panels (or vertical diaphragms). This Timber Engineering Bulletin introduces the engineering checks for overall building stability and the stability checks required for the wall diaphragms which provide shear (or racking) resistance to a platform timber frame structure. Robustness and disproportionate collapse design considerations for platform timber frame buildings are addressed in part 3 of this sub-series. Overall stability To achieve its stability, platform timber frame construction relies on the diaphragm action of floor structures to transfer horizontal forces to a distributed arrangement of loadbearing walls. The load bearing walls provide both vertical support and horizontal racking and shear resistance. Due to the presence of open-plan or asymmetric layouts or the occurrence of large openings in loadbearing walls, it may be necessary to provide other means of providing stability to the building, for example by the use of ‘portalised’ or ‘rigid’ frames or discrete braced bays as indicated in Figure 1. -
