【 摘 要 】

FRP (Fiber Reinforced Polymers) has been widely used in structure strengthening with the advantages of high strength, light weight, corrosion resistance and so on. FRP anchor is an effective anchoring method for external strengthening FRP laminate. In order to reduce cost and improve performance, B/C HFRP (hybrid of basalt fiber/carbon fiber reinforced polymer) anchor was made through mixing the basalt fiber with conventional CFRP anchors. The shear behavior and the anchoring performance of two kinds of FRP anchors under different diameter and arrangement methods were tested by several groups of experiments. The experimental results shew that the ultimate strength, material utilization and ductility of specimens were improved in different degrees, which indicated that it was practicable in concrete structures strengthening with this hybrid method.
