In this study, the fire test was performed under loading conditions, applied to a new concept reinforced fire protection that is suitable also to the reinforced concrete members by using the wire rope that can secure the lateral confinement of reinforcing bars, mixed with polypropylene fiber that is a reducing material of explosive fracture developed by the existing studies, steel fiber and hybrid fiber-cocktail in order to create a method to ensure the fire resistance efficiency for high-strength concrete of 60MPa. As a result of analysis, 60MPa strength concrete column recorded 146 minutes of fire-resistance performance under the hoop, and 180 minutes under wire the rope application.
