Abstract

This study was to define the strengthening effect of steel fibers in high strength RC columns. For this, ten specimens of columns were tested under cyclic lateral load and constant axial load. The testing parameters are steel fiber volume fraction of concrete and shear reinforcement ratio of hoop bars. Finally, the optimal content of steel fibers was evaluated as 1.0 - 1.5 % volume fraction of concrete.
