| الملخص: | This study investigated the compressive performance of 24 three-layered laminated bamboo specimens made with four different parameters, primarily bamboo species, adhesive type, lay-up pattern, and arrangement of laminated bamboo. The goal for this study was to investigate the compression parallel to the grain performance of laminated bamboo. A total of 288 laminated bamboo specimens were tested. Modulus of elasticity (MOE) and compressive strength were conducted to simulate the utilization of this material into construction material. The laminated bamboo produced were comparable to wood strength group A to B for vertical and horizontal arrangements and SG D for mixed arrangements. Laminated bamboo was produced based on Gigantochloa scortechinii and Gigantochloa levis and bonded with phenol resorcinol formaldehyde (PRF) and one-component polyurethane (PUR) adhesive. Four failure types were classified. All specimens experienced the elastic stage at the beginning of the loading process and then changed to elastic-plastic stage. There was a significant difference in the parallel and perpendicular lay-up for vertical, horizontal, and mixed arrangements.
