Bamboo as a natural resource is very common used in constructio, such as columns and beams, also can be used as architectural elements. The form of bamboo as a reinforcement is still under identification by many scholars to find an optimum shape and form of bamboo, thus it may be applied as concrete reinforcement since bamboo can improve concrete's flexural strength. An experimental test conduct in order to identify the role of perpendicular pivot end in bamboo reinforced concrete beams by observing the flexural capacity improvement. Four concrete beams with the dimension of 15 cm x 25 cm x 170 cm were made with 2 cm of square section of the lateral bamboo reinforcement and Ø8 - 100 steel rebar as the shear reinforcement to prohibit the shear failure. The beams were loaded under three-point bending with the point loading in the middle of the span. Based on the experimental result, the beams which equipped by the perpendicular pivot end could improve the load capacity up to 33% higher than the beam without the pivot end. This is proofed that the pivot can improve the flexural capacity of the bamboo reinforced beam and considerable to develop in the bamboo reinforcement beam. © Published under licence by IOP Publishing Ltd.
