Creating indicators of detail design changes for the building age determination of Japanese traditional architecture

为了了解日本木质传统建筑的年代，笔者提出了一种根据细部形状进行判定的方法。我已经创建了一个索引来了解这座建筑的年龄。本研究以13世纪至16世纪(大致在中世纪范围内)的木头(Kibana)和蛙腿(KAerumata)为例，考虑到京都、奈良等中心区与当地地区的差异，建立了建筑年限的判定指标。

I present a method for determining by the shape of the details in order to know the age of wooden traditional architecture of Japan. I have created an index to get to know the age of the building. In this study, for the wood ends(kibana) and frog legs(kaerumata), from the 13th century till the 16th century（in the range of the Middle Ages roughly ）, taking into account of the differences between central district such as Kyoto, Nara and local district, I have created the determination index on building age.
