BENDING EXPERIMENTS OF TIMBER JOINTS REINFORCED WITH CARBON FIBER

Abstract

This paper presents the results of bending experiments of traditional timber column joints reinforced by carbon fiber. The traditional timber column joint, which is called Kanawa-tsugi joint, is used for the test specimens. The unreinforced specimens broke at the joint and the maximum strength of the unreinforced specimen was much lower than the standard strength calculated on the assumption that the specimen is the uniform member without the joint. On the other hand, the maximum strength of the reinforced specimen was much higher than that of the unreinforced specimens. As the results, the reinforcing effect was verified.
