Fire Resistance Performance of High-Strength Concrete Columns Reinforced with Pre-Stressed Wire Ropes
In this study, the fire resistance performance of high-strength concrete columns was evaluated to see the influence of lateral confinement reinforcement with wire ropes for improving ductility, fire resistance reinforcement with fiber cocktail and load ratio. For this, loaded fire test was conducted under ISO834 standard fire condition. The axial ductility of the 60 MPa high-strength concrete column reinforced with pre-stressed wire ropes was improved and its fire resistance performance was also improved by 23% compared with its counterpart without wire ropes. The appropriate load for the 60 MPa concrete column reinforced with wire ropes was found to be 70% of design load. The fire resistance performance of the 100 MPa high-strength concrete column reinforced with pre-stressed wire ropes and fiber-cocktail was improved as much as 4 times compared with that reinforced with tie bars only. The appropriate load for the 100 MPa columns was found to be less than 70% of design load in order for the columns to secure required fire resistance performance.
