| Research Abstract |
To verify the safety limit deformation of the Japanese conventional post-and-beam wood residential construction with the mortar exterior wall and the light frame construction which have clarified datum to prove the safety limit deformation, the static lateral load tests were conducted to such old wood houses. As a result, 1) In the shear wall type of timber structures, the maximum loads were under about 1/30 rad shear deformation, and the collapse limit deformations were over 1/3 rad, 2) Maximum lateral capacity of the Japanese conventional post-and-beam wood residential construction with the mortar exterior wall was in the safety side in comparison with the precise seismic evaluation on"The seismic evaluation and reinforcement methods"published by The Japan Building Disaster Prevention Association.
