| Abstract: | The outstanding corrosion resistance performance of FRP bars can avoid the deterioration of concrete structure which is mainly caused by the bar corrosion. Therefore, concrete reinforced with FRP bars has attracted the attention of researchers at home and abroad. The bond behavior between FRP bars and concrete and the anchorage length of FRP bars are the main parameters which can influence the cooperative work of FRP bars and concrete. In this research, pull-out tests of different FRP bars embedded in concrete specimens are carried out. The damage mechanism and bond strength are analyzed. And the formula to estimate the anchorage length of FRP bars is derived, providing the theoretical guidance and basis for the practical engineering. |
