| Research Abstract |
The fire resistance degradation of glued laminated timber (GLT) beams is dominated by the loss of laminae, and depends on the adhesive shear strength in laminated wood. If the adhesive shear strength at 200℃ is enough to keep laminae from separating, the GLT beam specimens are expected to exhibit 45-minute quasi-fireproof performance. Adhesive shear strength test at 200℃ can be an alternative test method for full-scale fire test.
