| Abstract |
In this study, the structural performance of glued structural member made of small rectangular lumber was evaluated. The axial strength and elastic modulus of glued structural member were greater than those of the raw wood by 7.4% and 91.7%, respectively. It is estimated that failure modes and material imperfection caused these results. The flexural strength and flexural elastic modulus of glued structural member were about 13.5% lower than those of the raw wood after reflecting size effect. It is estimated that the lowering of these flexural performance was due to the fact that the tensile failure does not proceed smoothly and eventually occurred discontinuous failure at the interface region. The deflection ratio of both the raw wood and glued structural member at the 1st failure mode was about 1/110 which is about twice of the generally accepted serviceability limit of 1/240. This fact shows that both the raw wood and glued structural member satisfy the serviceability criteria sufficiently. |
