Development of a Safe and Simple Rapid Emergency Retrofitting Methodfor Disaster-damaged Structures

-Influence of Adhesive Resin on Shear Capacity Carried by Fiber Sheet-

Abstract

After an earthquake, it is necessary to quickly repair damaged structures in order to prevent further damage due to aftershocks; however, current retrofitting technologies are time-consuming or difficult to apply. The authors, therefore, propose an emergency retrofitting method for RC structures which is safe and easy to apply by developing fiber sheets with hydraulic resin, which can harden after exposure to water. In this paper, the adhesion behaviors of hydraulic and epoxy resins were investigated experimentally. It was found that although the adhesive strength of the hydraulic resin was low, ductile behavior was observed and the reinforcement effect was similar to that of the epoxy resin.[This abstract is not included in the PDF]
