Development of Emergency Rapid Retrofitting Method using Fiber Sheets Containing Hydraulic Resin

Abstract

The authors propose an emergency rapid retrofitting method utilizing fiber sheets containing hydraulic resin (TST-FiSH). The goals of this new method are to provide higher safety, speed, and ease of application compared to modern methods. The basic properties were evaluated by adhesion test, the repair effect was investigated by beam specimen, and the structural performance was confirmed by column specimen. As a result, in comparison with conventional fiber sheet wrapping method, TST-FiSH was confirmed that it can provide same repair effect on 1/10 application time. This paper reports these experiment results and the applicability of emergency rapid retrofitting method TST-FiSH.
