明治神宮宝物殿南倉の構造計画の特徴について

摘要

The Meiji Jingu Treasure Museum building, built in 1921 to commemorate Emperor Meiji and Empress Shoken, is known to architectural historians as the first example to try to express "Japanese-style" with the then modern technology of reinforced concrete. In this paper, however, delving into its original 87 structural working drawings in the shrine, the authors show its importance in technological history pointing out the reasonable structural modeling and adroit setting of the structural elements in it to make the design feasible with a long-spanned exhibition space (14.5 meters by 29 meters) poised by pilotis. The building can exemplify the highest level of the reinforced concrete technology in its early stage in Japan.%明治神官宝物殿は、周知のように明治天皇と照憲皇太后の御物の 収蔵と拝観を目的とした施設である。大正3年（1914）神社奉祀調 査会特別委員会にて建設が決定され、翌年に設計競技が行われた。
