This paper proposes a new type of the bamboo culm integrated bamboo bundles glulam using bamboo culm as skeleton, which solves the problem of the irregular size of the original bamboo and the hollow structures. A three dimension finite element model of bamboo culm integrated bamboo bundles glulam was established using continuum damage mechanics and cohesive element model. This failure and damage evolution process of bamboo culm integrated bamboo bundles glulam under the compression load was analyzed, and the process of adhesive failure between bamboo bundles was also analyzed. The results showed that 900 bamboo bundles layer were damaged, and 00 bamboo bundles layer were not damage. The load capacity of bamboo laminated glue material with the skeleton is 6 times higher than bamboo laminated glue material. Keywords—bamboo culm integrated bamboo bundle; glulam; failure; finite element
