Effects of species, adhesive, and structural configurations on compression parallel to the grain of laminated bamboo

This study investigated the compressive performance of 24 three-layeredlaminated bamboo specimens made with four different parameters,primarily bamboo species, adhesive type, lay-up pattern, and arrangementof laminated bamboo. The goal for this study was to investigate thecompression parallel to the grain performance of laminated bamboo. Atotal of 288 laminated bamboo specimens were tested. Modulus ofelasticity (MOE) and compressive strength were conducted to simulate theutilization of this material into construction material. The laminatedbamboo produced were comparable to wood strength group A to B forvertical and horizontal arrangements and SG D for mixed arrangements.Laminated bamboo was produced based on Gigantochloa scortechinii andGigantochloa levis and bonded with phenol resorcinol formaldehyde(PRF) and one-component polyurethane (PUR) adhesive. Four failuretypes were classified. All specimens experienced the elastic stage at thebeginning of the loading process and then changed to elastic-plastic stage.There was a significant difference in the parallel and perpendicular lay-upfor vertical, horizontal, and mixed arrangements.
