Abstract:

Flexural failure is a critical concern in bamboo-reinforced concrete, where bending forces cause tensile cracks to develop and propagate, ultimately leading to structural collapse. This research investigates the failure in terms of flexure of bamboo-reinforced concrete beams through experimental analysis, including compressive and tensile strength tests, three-point bending tests, and load-deflection and load-strain relationships. The results show that the beams achieved an average flexural stress of 37.7099 N/mm², with maximum displacements before failure ranging from 7.43017 mm to 9.42547 mm. Load-deflection analysis showed that the 1100 × 300 × 300 mm beams exhibited greater stiffness and lower deflection compared to the 1100 × 150 × 300 mm beams, reinforcing the role of beam size in flexural performance. Strain measurements confirmed that compression occurred at the top of the beams, while tension at the bottom led to crack initiation and eventual failure as the loads applied exceeded the material’s capacity. The findings highlight the suitability of bamboo as an alternative material for reinforcement while emphasizing the importance of material strength, strain distribution, and bond efficiency in resisting flexural stresses and delaying failure.
