Experimental Study on Behavior of RC Beam Strengthened with Ridged Aramid Fiber Plate Strip

Abstract:

In this study, to evaluate the bending performance and the shear performance of Aramid Fiber Plate Strip with enhanced attachment, 8 specimens were made for experiment. Most flexural failure specimens showed AFPS rip-off failure or separation failure. In the shear failure specimens, the specimens showed a brittle failure in which the concrete compression edge was broken. Compared with the control beam, the maximum ultimate strength increased by 164~193% for the flexural failure specimen, and by 218~259% for the shear failure specimen. The ductility, however, decreased steeply in the shear-failure specimen as the amount of reinforcement grew.
