Outline of Final Research Achievements

The physical properties of white birch and Erman's birch were determined through experiments. Finite element analysis was employed to simulate the bending performance of glued laminated timber (GLT) using white birch and Erman's birch for the outer layer. The physical properties obtained from the experiments were incorporated into the finite element analysis. By determining the Young's modulus and strength in each direction, we were able to ascertain the post-yield behavior during the bending test of the GLT. The analytical results were found to be consistent with the experimental results

Academic Significance and Societal Importance of the Research Achievements

これまでシラカンバ、ダケカンバの弾性常数は明らかでなかった。弾性常数、強度を整備し、かつそれらを利用して構造要素を弾性域を超えた非線形領域まで解析を行ったことに研究意義がある。
