摘要：

Hybrid bonding FRP-reinforced concrete structures has been verified through tests for improving the material efficiency and structural bearing capacity, but detailed analysis of the anchor distribution are still scarce, especially considering the beam length parameter, therefore, a numerical simulation is conducted to study the effect of anchors on the flexural behavior of externally bonded FRP-reinforced concrete beams. The numerical model is verified first, and the effect of the beam length parameter on the anchor distribution is analyzed. It is found that the bonding behavior of the beam with the same cross section is closely related to the moment, regardless of the beam length. For beams with the same design moment, the anchor spacing is suggested to increase with the beam length but remain the anchor width. A design methodology of hybrid bonding FRP-reinforced concrete beam that considers different failure modes are proposed, and the predicted flexural capacity is verified by the test result.
