摘要：The structural components of reinforced concrete that withstand the tensile stress will be bonding stress affected by the friction between the reinforcing bar and the concrete. Anchoring depth, reinforcement diameter, and concrete quality are commonly assumed to influence bond strength; besides, the support distance of reinforcement may be one of the influencing factors. The samples in this study were cylindrical specimens with a diameter of 15 cm and 20 cm for the concrete compression strength and the bond-strength test, respectively, and double-L size 30 x 20 x 7.5 cm for the concrete shear test. Variables in this study include variations in the support distance represented by variations in the diameter of the supporting plate hole, namely 10 mm, 35 mm, 60 mm, 85 mm, and 110 mm. Plain reinforcement with a diameter of 10 mm was anchored at 150 mm depth in the centre of the concrete cylinder. The experimental results obtained 26.49 MPa and 10.86 MPa for concrete compression dan shear strength, respectively. Based on various diameters of the supporting plate hole, the hole diameter of 10 mm to 60 mm had a stable increase in bond strength and a significant decrease when a larger hole diameter was used.
