Crack behavior study of bamboo reinforced concrete beam with additional pegs in reinforcing

This research concerned about the effect of additional pegs along the bamboo reinforcement in order to increase the bond strength of reinforcement in bamboo reinforced concrete beam. A new technique was developed in this research to improve the mechanical properties of bamboo reinforcement and improve composite strength between bamboo and concrete. Wooden pegs and hose clamps ring pegs are used as adders bonding strength between concrete and reinforcement. The level of flexural performance after concrete cracking occurs, is an important factor that can be used to assess the effect of the pegs on the flexural performance of the bamboo reinforced concrete beam. The results of this study indicate that bamboo reinforcement with additional pegs develops adequate bonding with the concrete matrix, but a smaller interval of pegs reduces the bonding strength. Installation of hose clamp pegs increase the bond slip parameter from 1 MPa to 1,6 MPa.
