Abstract

Failed of bond-slip interaction between bamboo reinforcement and concrete are main factors of flexural failure at bamboo's reinforced concrete beams. To increase bond-slip interaction between surface of bamboo reinforcement and concrete has been done using coating treatments with water-resistant material, the addition of hooks, wire rope wrapping, and others. With the treatments, concrete beams with bamboo reinforcement able to increase capacity, but the pattern still shows slip failure. The aim of this research is to improve bond-slip interaction between bamboo reinforcement and concrete to reform the flexural behavior pattern of concrete beam using a hose clamp. This research used bamboo petung (Dendrocalamus asper) 2-3 years. Dimension of bamboo reinforcement is 15 mm x 15 mm. Dimension of concrete beam is 120 mm x 200 mm x 2100 mm, with percentage of tensile reinforcement (ρ) about 4.68% and compression reinforcement (ρ ') about 1.875%. Shear strength reinforcement using steel bar with diametre of 6 mm. Four beam specimens casted with four different treatment, i.e: normal reinforcement, reinforcement with hose clamp, reinforcement with water-resistant coating, and reinforcement with water-resistant coating and hose clamp. Beam tests performed using four-point load. The test results showed flexural capacity, ductility, and stiffness of the beam with bamboo reinforcement which coated by water-resistant material and hose clamp has increased compared to the other beam. All beams shows crack and collapse by slip failure, but beams with bamboo reinforcement which were coated by water-resistant materials and hose clamp has many spread crack before it collapses Keywords: Bamboo reinforced concrete, hose clamp, bond-slip interaction, flexural capacity.
