Summary
Recently, the numerical value and the technical information of the design are insufficient though an increase of a large timber construction is expected. In this research, a high load carrying capacity shear wall with thick plywood sheathings for the large timber construction was developed, and its static bearing force was confirmed experimentally. And the bearing force of the shear wall was calculated by using past numerical analysis methods. As a result, the development of the wall having the target bearing force succeeded, and the numerical analysis method could be applied to the high load carrying capacity shear wall.

Summary
As timber tends to be weak against the load perpendicular to grains, it can be important to study the consequences of applying loads perpendicular to larch cross-laminated (CLT) composed of multiple larch laminae. Compressions tests were conducted perpendicular to the in-plane and out-of-plane grains of Japanese larch CLT. Out-of-pane average compressive strenth, average yield strength, and average compressive stiffness perpendicular to the grain of the larch CLT were 11.94 N.mm2, 7.30 N/mm2, and 7.30 N/mm2, respectively, whereas the in-plane average compressive strength, average yield strength, and average compressive stiffness perpendicular to the grain of the CLT larch were 21.48 N/mm2, 21.18 N/mm2, and 18.72 N/mm2, respectively. The in-plane compressive strength and yield strength showed a statistically significant relationship with the density fo the CLT, the modulus of elasticity measured by longitudinal vibration (MOElv), and the average MOElv of the laminae constructing the cross-laminated timber. The in-plane yield strength was affected by the MOWlv of the outer laminae and the average MOElv of the larch cross-laminated timber. The compressive strength properties were most affected by the loading surface of the CLT. The variation between the moisture content and compressive strength properties of the CLT, however, was not statistically significant.
