GFRP 보강근을 적용한 콘크리트 부재의 기존 연구 고찰 및 연구동향 분석

초록

In Korea, the practical applications of GFRP-reinforced concrete are still limited despite the establishment of its design standards because these domestic standards were established by referencing provisions that were conservatively written in foreign codes. This conservative approach poses a substantial challenge for the domestic adoption of GFRP-reinforced concrete. Moreover, this challenge is accentuated by the varying quality of GFRP products in the Korean market compared to international standards. To address this, various studies have been conducted domestically and internationally to revise these design codes. For beam members, the research is mainly focusing on verifying the degree of conservativeness in the design values of the current codes. For column members, numerous studies are investigating the compressive capacity of the GFRP reinforcement itself. Furthermore, research on various other concrete members is actively being conducted to propose new design equations that can be directly incorporated into the revised design standards.
