Abstract

An experimental study was conducted to study the application of extemally bonded FRP (Fiber Reinforced Polymer) sheets on the transverse beani of RC (Reinforced Concrete) bridge frames. In shear strengthening beams using FRP sheets, full wrapping is not always possible and in U-wrapping, debonding failure of FRP sheet limits the proper utilization of its strength. Therefore, in this research FRP sheets were mechanically anchored. A total number of six specimens with different wrap configurations and mechanical anchorage schemes were tested. Experimental results showed that a proper selection of mechanical anchorage scheme for FRP sheet in V-wrap portion is necessary for the significant enhancement of shear strength of RC beam close to that of a fully wrapped beam.
