seismic performance evaluation of traditional wooden house
DESCRIPTION
A large number of wooden houses built by Japanese traditional wooden construction method now exist in Japan. In general, the seismic performance of these traditional wooden houses is considered to be low because their shear wall ratios are small. The objective of this study is to confirm experimentally the seismic performance of traditional wooden houses. The loading test was held in 2004, when I worked at Toyohashi Univ. of Technology. The paper was reported in 2005 and the oral presentation was at the World Conference on Timber Engineering 2006, when I was in Takamatsu National College of Technology [1]. [1] Takamatsu NCT is now Kagawa NCT.TRANSCRIPT
