Comparative Study of Steel Reinforced Concrete Beams with Bamboo Reinforced Concrete Beams

Abstract

The Studies conducted to compare the ability of steel reinforced beams with bamboo of reinforced beams. For steel reinforced beams  used tensile reinforcement with a diameter of 16 mm, while dimension bambu reinforced is 21 x 10 mm, and shear reinforcement is 12 mm. Compressive strength of concrete beams RCB-BR) with bamboo reinforcement is 51.70 MPa, then (RCB-SRBF) 54,426 MPa is the strength of steel reinforced fiber concrete beam, and for reinforced concrete beams (RCB-SR) without the addition of fibers is 58.77 MPa. The beam bending test was carried out at 28 days old, by producing a maximum load value of 10.90 tonnes successively; 27.00 tons and 26.00 tons for each beam bending test specimen. In the bamboo reinforced concrete beams, the value of flexural capacity is 1.104, then the reinforced beam with the addition of fiber is 1.422, and the reinforced concrete beam without the addition of fiber is 1.331. A review of the ductility value obtained the greatest value in steel reinforced concrete beams with the addition of bamboo fibers, namely 1.823, then steel reinforced concrete beams without the addition of fibers with a ductility value of 1.713. The lowest ductility value of 1.322 was obtained in testing bamboo reinforced concrete beams. The RCB-BR has defection maximum is 28.70 mm with yield deflection 21.07 mm, and then RCB-SRBF has deflection maximum 18.70 mm with yield defection 10.26 mm, and RCB-SR 18.47 mm; 10.78 mm.This condition indicates that the use of bamboo reinforcement has not been able to completely replace steel reinforcement.
