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.

本研究以日本传统木结构为研究对象，通过对日本传统木结构的土墙与木节点的强度性能进行研究，以便于修复。(a)通过试验计算出了土的总截面和局部截面抗压强度、抗剪强度和抗弯强度。(b)为了研究搭接长度对该节点抗弯、抗压性能的影响，对常用于框架尤其是柱修复的Kanawa-tsugi节点进行了试验研究。研究结果表明：（1）水泥混凝土的整体和局部抗压强度、抗剪强度和抗弯强度分别为0。31N/mm ~ 2，0. 66N/mm ~ 2，1. 04 N/mm 2和0. 68N/mm ~ 2。(2)Kanawa-tusgi关节在弯曲时有一个强轴和弱轴。(3)搭接长度越长，弯曲强度越高，但塑性越小。(4)这是几乎相同的抗压强度，但它不是基于搭接长度。
