Abstract
In this paper, a new bamboo glulam is proposed. The material fully utilizes the characteristics of the hollow bamboo culm and easy integration of bamboo bundles, and realizes a hollow bamboo glulam. A three-dimension finite element model of the bamboo culm integrated bamboo bundle glulam was established using the continuum damage mechanics and cohesion element model, and the failure process of the glulam material under the tensile load was analysed. The results show that the fibers in the 1st and 2nd plys of the 90° bamboo bundles were stretched and failed, and the fibers in the 1st and 2nd plys of the 0° bamboo bundles didn’t fail. 90° bamboo bundles ply 2 matrix compression failure occurred, the bamboo culm integrated bamboo bundles glulam tensile strength is 4 times higher than bamboo bundles glulam.
