| Abstract |
This paper presents the results of an experimental study on the bond strength of glass fiber reinforced polymer (GFRP) bars under repeated load. The experimental program consisted of 36 concrete cube specimens subjected to four different loading patterns. The test results showed that the bond failure of steel and GFRP-HW bars to concrete occurred mainly at the interface 1 (interface between the exterior resin layer and the concrete), but GFRP-SC bar to concrete bond failed mainly at the interface 2(interface between the resin layer and bar fiber). In addition, the cyclic load reduced the bond strength of GFRP rebars under monotonic load. |
