Abstract
The purpose of this study is to evaluate the shear strength of steel fiber reinforced concrete columns quantitatively through the experimental program. For this purpose, the volume fraction of steel fiber is determined to main parameter (0%, 1%, 2%), and the cyclic lateral loading tests of columns were performed with constant axial loads. According to the test results, the shear strength of the column with 1% of steel fiber increased 1.61 times and shear strength of the column with 2% of steel fiber increased 1.67 times compared to RC column. Also, it was investigated that the cracks are distributed and angle of cracks is reduced in specimens with steel fiber. This resulted in an increase of the number of transverse reinforcement located on the crack face. Therefore, the shear strength of columns was evaluated by dividing the shear strength contribution by the concrete, transverse reinforcement, and the shear strength increase by the steel fiber. As a result, the shear strength contributions of concrete increased about 29% with 1% of steel fiber and increased about 36% with 2%. Also, the shear strength contributions of transverse reinforcement increased when steel fiber is mixed.
