In this study, the hybrid fiber effect and tensile behavior of hybrid fiber-reinforced cement composites (FRCC) with hooked steel fibers (HSF, Length: 30mm) and smooth steel fibers (SSF, Length: 13mm) were evaluated under the static and dynamic loading tensile conditions. As a result, when SSF and HSF were hybridized, SSF improved the pull-out resistance of HSF, thereby improving tensile properties and dynamin increasing factor under the static and dynamic loading conditions. Through this, it was confirmed that the appropriate combination of long fiber and short fiber had a positive effect on the FRCC.
