Summary:To examine the compression properties of structural members, the compression and bearing tests were conducted in parallel- and perpendicular-to-grain loading using domestic Japanese larch (Larix kaempferi (Lamb.) Carriere). Compression (bearing) properties with the length of a specimen and the contact length of the bearing plate were investigated, and deformations at each specimen length from the point of bearing force were measured to evaluate the effective end distance tabulated in the present practice (Korean Building Code). Compression (bearing) properties varied with the size of the bearing plate, and the end distance for dowel-type fastener taken into consideration of the specimen's deformation, for the safe design, should be applied with over 7 D. 구조부재의 압축성능을 검토하기 위하여 낙엽송 소재에 대해 섬유방향 및 섬유직각방향 압축시험을 행하였다. 시험편의 길이와 가압판의 크기에 따른 압축성능을 검토하였으며 현행 기준의 최소끝면거리의 적정성에 대해 검토하기 위하여 다우얼 지압지점으로부터 시험편의 섬유방향에 대해 변형율 변화를 측정하였다. 가압판의 크기에 따라 압축성능은 다르게 나타났으며, 다우얼형 파스너의 최소끝면거리(end distance)는 내부변형을 고려할 경우 현행 7 D보다 높게 적용하여야 안전한 것으로 나타났다.
