Shear reinforcement structure using fiber sheet and clips for shear reinforcement substitution

YANG KEUN HYEOK / MUN JU HYUN / LEE YONG JEI / HWANG YONG HA

Disclosed is a shear reinforcement structure, which can be easily configured in a closed type regardless of arrangement positions of a main reinforcing bar and a compressed reinforcing bar by using a fiber sheet having excellent flexibility, maximize shear resistance performance of a beam, complete arrangements by using a simply prefabricated clip so that constructability is improved, and perform vertical and horizontal reinforcement at the same time by using a net-shaped fiber sheet so that the shear resistance and diagonal tensioned crack resistance are excellent as compared to the shear reinforcing bar. To this end, the shear reinforcement structure includes a net-shaped tension member for shear reinforcement and a fixing clip.

유연성이 우수한 섬유시트를 이용하여 주철근 및 압축철근의 배근위치에 관계없이 손쉽게 폐쇄형을 구성하고, 보의 전단저항성능을 극대화하고, 조립이 간편한 클립을 이용하여 배근을 완료할 수 있어 시공성이 향상되고, 특히 망상형 섬유시트의 사용으로 수직 및 수평 보강을 동시에 수행함으로써 전단철근에 비해 전단저항성능과 사인장 균열저항성능이 우수한 전단보강 구조가 개시된다.
