抄録

In order to investigate the structural performance of glulam beams with holes, full-scale bending tests and FEM analyses were carried out. Two 9m long glulam beams with 9 round holes were used. The parameter of the tests was hole placement, the deviation of hole center was 1/7.2 of beam height.<br>As a result, shear failure occurred in both beams, and the effect of the deviation on strength was considered to be small.<br>Comparing between tests results and FEM results, we found that we could grasp the situation of tests using FEM results. But that’s the problem that the assessment of shear collapse is not established.
