Shear Capacity Estimation of SFRC Beam with Stirrups Considering Steel Fiber Strengthening Factor

강섬유 보강계수를 사용한 전단보강 SFRC보의 전단내력 예측

The purpose of this study is to estimate the shear strength of SFRC beam that has stirrups. To achieve the goal of this study, two stage investigation, which is material and member level, is studied. From the reviewing of previous researches and analyzing of material and member test results, strengthening parameter of SFRC is defined as steel fiber coefficient. Based on above results, steel fiber strengthening factor is proposed. Therefore, shear strength equation of SFRC, which is considered the steel fiber strengthening factor, is proposed by regression analysis of test results.
