Description
For the anchorage of bamboo reinforce concrete structures, it is difficult to attach plates or hooks to the ends of bamboo reinforcements. The mechanical anchorages of steel reinforcement bars are tried to use in some construction systems. In this study, twenty-one pull-out tests carried out to investigate the load carrying capacity of bamboo reinforcement with mechanical anchorage. The load carrying capacity of bamboo reinforcement is discussed by comparing with the steel reinforcement with 180-deg. hook. In comparison with the steel reinforcement with 180-deg. hook, the deformation performance of bamboo reinforcement with mechanical anchorages is not good, but the load carrying capacity of bamboo reinforcement is improved by use of anchorages. The equation to predict the pull-out load carrying capacity of mechanical anchorage is proposed as the sum of bond and adhesive force. The predicted capacity agrees with the experimental one that was obtained in this experimental study.
