Abstract: In order to study the adhesion properties of basalt fiber reinforced composites (BFRP) ribs and steel-polyvinyl alcohol hybrid fiber reinforced cement matrix composites (steel-PVA mixed ECC), a series of experimental studies and analysis were carried out. The results show that in the range of test steel fiber doping, the mechanical properties and interfacial adhesion properties of the steel fiber doping have a positive effect on the mechanical properties and interfacial adhesion properties of the specimen, and the cubic compressive strength of the steel-PVA hybrid ECC specimen increases with the increase of the amount of steel fiber, and the increase of the steel fiber doping can significantly improve the bonding strength of the BFRP rib and the steel-PVA hybrid ECC; In the test BFRP rib diameter and anchor length range, the diameter of the BFRP rib and the anchoring length have a negative impact on the interfacial bonding performance of the specimen, which increases the diameter of the BFRP rib and the anchoring length. The bond strength of BFRP ribs and steel-PVA hybrid ECC specimens has been reduced to varying degrees. The bond strength of the central pull specimen is basically between 5 and 12 MPa. Among them, the specimen with 0.9vol% steel fiber doping, BFRP rib diameter of 8 mm and anchor length of 5d has the largest bonding strength of 16.82 MPa, while the specimen with unaddressed steel fiber, BFRP rib diameter of 12 mm and anchor length of 5d has the smallest bonding strength, which is 5.46 MPa. The central pull specimen failure mode is divided into BFRP rib extraction failure and BFRP tendon extraction-steel-PVA mixed ECC cleavage failure (pulling-splitting failure), all specimens are basically BFRP rib extraction failure, only a small number of specimens are pulled out-cleavage failure, and only the surface of the specimen with the pull-split failure is broken in contact with the BFRP tendon. The bond-slip model established by using four-stage expressions (micro-slip section, slip section, descending section and residual section) expression can accurately reflect the bonding slip process of BFRP rib and steel-PVA mixed ECC. Based on the measured bond strength and compressive strength values of the test, an expression is established to calculate the basic anchor length of the BFRP rib.
