Abstract

This study began as part of a study to evaluate the performance of walls in traditional architecture. The composition of the specimens is as follows. All Inbangs are the same(120×120mm), and the size of Jung-gis was determined to be 1/3(40mm), 1/2(60mm), 2/3(80mm), and 4/5(96mm) of the size of Inbang, with a total of 15 specimens, 3 each. As a result of the experiment conducted through displacement control of 1mm/min, it is divided into an slip section, an elastic section, and a post-yield section, and as the size of Jung-gis increases, the initial stiffness and yield strength increase. The overall load-displacement relationship was mostly due to partial compression deformation between Inbang and Jung-gis. Among them, the specimen(A) with the largest slenderness ratio showed large buckling deformation at large deformation. The fracture shape of the specimen showed more deformation in Inbang than Jung-gis. This is because inbang resists force in the direction perpendicular to the wood fibers. The results of the experimental specimen show similar results to the Korean and Japanese construction design code. Even if it is within the range of the standard, further consideration of the analysis method is needed regarding the slenderness ratio.
