| Research Abstract |
In this study, the following experiments were conducted for the purpose of clarifying strength performance of an earth-wall and timber joints on Japanese traditional timber structure in order to repair it.(a) A compressive strength for gross section and partial section, a shear strength and bending strength of an earth were figured out by the way of experiment.(b) Kanawa-tsugi joint which was often used in repairing framework especially column was tested in order to figure out an effects of a lapped length of this joint in bending and compressive properties. As the results it were found followings ;(1) a compressive strength for gross and partial section, a shear strength and a bending strength was 0. 31N/mm2, 0. 66N/mm2, 1. 04N/mm2 and 0. 68N/mm2, respectively.(2) Kanawa-tusgi joint had a strong and weak axis in bending.(3) It was in the tendency that the longer a lapped length was, the stronger a bending strength was, but the smaller its ductility was.(4) It was the almost same compressive strength but it was not based on a lapped length.
