| description | This study investigated the mechanical properties of bamboo-wood composite beams by conducting four-point bending static load tests on eight laminated beams. It was shown that a new bamboo-wood composite material was obtained by laminating denser laminated bamboo to the surface of timber panels employing hot pressing. Failure of the beams was mainly due to interlaminar shear damage and brittle fracture at the bottom. The test results showed that the polyurethane and epoxy binders ensured good interlaminar bonding properties. In the same adhesive specimen, the increase in the number of bamboo panels increased the ultimate load-carrying capacity of the bamboo-wood composite beams. The predicted load capacity using the equivalent section calculation method agreed well with the experimental results and was effective for assessing the mechanical properties of bamboo-wood composite laminated beams. |
