Abstract

This paper summarizes three different FRP shear reinforcement methods based on the available research results of FRP shear reinforcement beams. The experimental investigation history of externally bonded method and near surface mounted method is introduced and the advantages and disadvantages of each method are discussed. The article also points out that the ETS technique is a blank in domestic research and application. The experimental study history and status of the embedded through-section method are summarized and expounded according to the existing foreign literature in this field, in order to provide a reference for relevant domestic research and application. Finally, some suggestions of experimental study on FRP shear-strengthened are presented, and the research direction is also prospected.
