콘크리트는 안전성과 경제성이 우수한 재료로 인식되어 많은 사회기반시설물의 건설재료로 이용되어 왔으나, 최근에는 노후화 현상 등으로 인한 성능저하가 발생하고 있으며 이는 직·간접적으로 경제적·인명적 피해의 원인이 되기 때문에 여러 가지 보강을 실시하고 있다. 본 연구에서는 복합섬유소재를 활용하는 보강공법을 포함한 다양한 보강공법에 대한 성능비교 실험연구를 수행하고 분석하였다.

Recently, most over the world infrastructure consists of reinforced concrete structures. Reinforced concrete structures are recognized as materials with excellent safety and economy. However, aging occurs with the construction phase and the passage of time. As a result, facility performance is reduced and maintenance costs are greatly increased. Thus, deterioration of structures directly or indirectly causes economic and human damage and requires repair and reinforcement to prevent it. Also, fiber composite materials are utilized as reinforcements and panel types as reinforcement methods. Therefore in this study NSM(NSM : Near Surface Mounted), EP(EP : External Prestressing), EB(EB : External Bonding), and SE(SE : Section Enlargement) methods are used to perform comparative analysis with ordinary reinforced concrete structures. Also, It can be used as a design guideline database based on experimental results.
