STUDY ON FLEXURAL PERFORMANCE OF WOODEN MEMBERS WITH THE PARTIAL LOSS OF SECTIONAL AREA

In this paper, the bending experiment on the wooden members with partial loss of sectional area was done. This bending experiment has three parameters such as the minor side of member, the direction and the length ratio of partial loss. Moreover, the influence of the partial loss of sectional area was modeled with the rotational spring, and the formula for the rotation rigidity was derived from the experimental results. The formula for the rotation rigidity was obtained from the length and the flexural rigidity in the partial loss of sectional area. Then the bending experiment on the specimens with the partial loss of sectional area to assume the post-Sashigamoi joint was done. And the effectiveness of the formula for the rotation rigidity was examined from these experimental results.
