31. Yasuhiro Nambu, Mina Sugino, Sunao Kobayashi, Noriko Takiyama, Chiaki Watanabe, Yasuhiro Hayashi, Structural investigation and seismic performance evaluation of traditional wooden houses in Gojoshinmachi in Nara prefecture in Japan, WCTE 2016 - World Conference on Timber Engineering, 2016.01, Gojoshinmachi in Nara, which was designated as Important Preservation District for Groups of Historic Buildings (IPDGHB) in 2010, has a large number of traditional wooden houses. In this area, damage resulting from the next Nankai earthquake is concerned. Therefore, to understand structural characteristics of the houses in Gojoshinmachi, first, we conduct structural investigation of several houses and evaluate their seismic performance. Next, we compare structural characteristics among traditional wooden houses in other 6 regions. The following can be stated. a) The width of frontage of the houses in Gojoshinmachi is large. b) Yield base shear coefficients Cy in both weak axis and strong axis are small. Moreover, Cy of some houses in weak axis falls below 0.1. c) The average of Cy is smaller than other regions. This is because there is a tendency that the width of frontage of house increases, the value of the yield base shear per unit first floor area decreases..

Saki Ohmura, Yasuhiro Nambu, Yoshihiro Shibuya, Mina Sugino, Yasuhiro Hayashi, Experimental analysis on seismic performance evaluation of traditional timber frame structures with large hanging walls, WCTE 2016 - World Conference on Timber Engineering, 10.3130/aijs.81.1479, No.727, 2016.01, In Japan, there are a lot of traditional timber buildings. In our investigation of the traditional timber houses, the structures which consist of tall hanging walls and beams called Sashigamoi in Japanese were found. The purpose of this study is the demonstrative investigation of the mechanical characteristics of the timber frame structures with large hanging walls aiming for construction of a reasonable and practical seismic evaluation method. In this paper, we performed the static loading tests of the historical timber frames with large hanging walls and analyze the test results in detail. As a result, it is revealed that there is room for improvement on the current method of seismic evaluation on the frames with hanging walls as for evaluation on the restoring force characteristics and the possibility of breakage of columns..
