The purpose of this study was to determine the effect of variations in overlap length and stirrup spacing of Apus bamboo on (1) the flexural capacity, (2) deflection, (3) crack behavior of reinforced concrete beams. The design of this study was experimental, and the data obtained from the test results were described. The parameters measured in this study could be determined by testing the specimens of 12 bamboo reinforced concrete beam models with an overlap length of one-fifth of the total stirrup length and stirrup spacing of 2.5 cm (A1, A2, and A3), 5 cm (B1, B2, and B3), 8 cm (C1, C2, C3), and an overlap length of one-half of the total stirrup length with a stirrup spacing of 5 cm (BY1, BY2, and BY3) and 8 cm in width, 10 cm in height and 80 cm in length. The concrete quality was f'c = 25 MPa. The research results showed that (1) the bamboo reinforced concrete beams with a stirrup spacing of 2.5 cm, 5 cm, and 8 cm had a flexural capacity of 1153.33 kg, 1280 kg, 1152.33 kg and 1270 kg, (2) a maximum deflection of 6.76 mm, 7.95 mm, 7.83 mm and 8.75 mm, and 3) flexure-shear cracks occurring in all beams. © 2017 Author(s).
