In this paper, we carried out loading test and finite element analysis, and studied the behavior of partial compression perpendicular to grain considering the distance from the end of member to the bearing area, the depth of member and the bearing length in order to investigate suitability of the allowable partial compressive stress perpendicular to grain of Japanese standard for member with large cross-sectional area like Heavy Timber. As a result, we clarified that the allowable partial compressive stress perpendicular to grain of Japanese standard wasn't reasonable for the actual behavior of partial compression perpendicular to grain, and suggested new leading method using modulus of apparent elasticity, strain-energy and the ratio between depth of member arid bearing length as the parameter, and the concrete numerical value for the allowable partial compressive stress perpendicular to grain.
