An Experimental Study on Shear Behavior of High Strength Reinforced Concrete Beams using Input Steel Fiber

강섬유을 혼입한 고강도 철근콘크리트 보의 전단거동에 관한 실험적 연구

Recently , the use of steel fibers has been increased in flexural members and beams of concrete structures ; such as bridge decks, highway roads, runway of airport , buildings , ete.. An experimental investigation of the shear behavior of high-strength reinforced concrete beams using input steel fiber was conducted. However only a few experimental tests have been carried out under static loading . The static test was carried out to measure the ultimate load, the initial load of flexural and diagonal cracking , crack patters, fracture modes. The load versus strain and load versus deflection relation were obtained from the static test.
