The effect of performance of beam reinforced concrete beams with screw toward share test

Abstract

The potential of bamboo as one of the materials that have a high tensile strength of parallel fibres is expected to be an alternative material to replace steel reinforcement. This research would develop bamboo as reinforcement which is applied to the structure of reinforced concrete beams by making modifications that utilize as much as possible the strongest part of bamboo, namely on the skin. In the modification made on bamboo reinforcement, there are 2 types of reinforcement, namely bamboo reinforcement using 1-cm screw nails and bamboo reinforcement using 11/2 cm screw nails, while the distance between screw nails is taken at 75 mm. Reinforcement area there is 4 strain gauge. Beam structure behaviour between variation 1 and variation 2 did not experience significant differences. The highest maximum load reaches 50.12 kN and also with the largest deflection of 18.73 mm. The performance of bamboo reinforced concrete beams can be said to be good with a significant increase in beam ductility with a ductility value of 29.93 - 27.61% when compared to steel reinforced concrete beams. In general, the performance produced by bamboo reinforced concrete blocks can be said to be good with a significant increase in beam ductility.
