The performance of the concrete beam depends on many aspects including reinforcement type, their architecture in beam, bond behavior between concrete and reinforcing bars and many others. However, the aspect in this chapter is placed in bond behavior of the composite bars and concrete. This behavior is crucial in terms of effective performance of concrete beam, weak bond connection results in pre-failure of the member. To investigate the adhesive behavior the pull-out tests were performed for pultruded composite rebars and experimental data were correlated with available models that predict this behavior. A good agreement of experimental results with analytical models was found.

摘要

The performance of the concrete beam depends on many aspects including reinforcement type, their architecture in beam, bond behavior between concrete and reinforcing bars and many others. However, the aspect in this chapter is placed in bond behavior of the composite bars and concrete. This behavior is crucial in terms of effective performance of concrete beam, weak bond connection results in pre-failure of the member. To investigate the adhesive behavior the pull-out tests were performed for pultruded composite rebars and experimental data were correlated with available models that predict this behavior. A good agreement of experimental results with analytical models was found.
