(Peer review + Similarity) Bridge Structure from Bamboo Reinforced Concrete Frame

Abstract— The use of bamboo to replace the steel reinforcement starts from the fact that bamboo has high tensile strength as high as steel. As a renewable material bamboo has much benefit for green construction material. Bridge frame structure is one of structure that can use the bamboo reinforced concrete. The research aims to find out (1) the strength of the bamboo reinforced concrete bridge frame, (2) knowing the behavior of failure characteristic of bamboo reinforced concrete frame, (3) know the strain stress relation on bamboo reinforced concrete element (4) the load deflection relation on bamboo reinforced concrete bridge. Bamboo reinforced concrete bridge frame has span 3000 mm, and 2200 mm wide made from precast frame bamboo concrete composite. The testing consists of laboratory tests and field tests. In the laboratory tests, the frame was loaded until collapse, and on field test the bridge was loaded with full vehicle load. The results of laboratory tests show an appropriate result between theoretical calculations and experimental testing. Fields tests results show that the bridge was capable of carrying full vehicle loads. The bridge was made with precast system for truss and transverse beam, and cast in place system for vehicle floor.
