In this research article, a novel approach to connect bamboo was designed and evaluated in order to integrate sustainable material into modern structures. Several bamboo joints for culm connection were designed based on strength and durability under various loading capacity. The conceptual joints were manufactured and subjected to destructive testing on the Universal Testing Machine, Testometric M500-50AT. From the mechanical properties generated, final modifications and refinements were incorporated into the joint design. Self-drilling metal screw joints were found to be the strongest with a maximum resisting force of around 11 kN in compression and 10 kN in tension. Riveted joints were the second strongest joint, while tightening ring joints, the weakest among the three, could only resist a peak load of 747 N in tension. The joints, designed with metal fittings, proved to be more practical for utilization in assembly design.展开更多
