Behavioral Characteristics of Reinforced Concrete Beams Shear-strengthened with Basalt Fiber Sheets based on the Shear Span/Depth Ratio
이 연구는 바잘트 섬유시트로 전단보강한 철근콘크리트 보의 전단경간비에 따른 구조물의 구조적 거동을 실험을 통해 확인하였다. 철근콘크리트 보의 전단보강은 무보강, 45도, 90도, U형보강을 변수로 두었으며 전단경간비에 따른 실험결과 U형으로 보강하였을 때 철근콘크리트 보의 전단보강효과가 높음을 확인하였다.
In this study, the structural behavior of reinforced concrete beams shear-strengthened with basalt fiber sheets based on the shear span ratio was investigated via experiments. The experimental parameters for the shear strengthening of reinforced concrete beams comprised beams without reinforcement and 45°, 90°, and U-shaped reinforcements. Experimental results showed that the shear strengthening effPect of the reinforced concrete beams was excellent when the basalt fiber sheet was subjected to U-shape reinforcement.
