Abstract
This study evaluates the fire resistance performance for 60MPa high strength concrete reinforced by recycling polyethylene-terephthalate(PET) fiber(fiber content : 0.05 vol.%). Because there is no fire resistance test results for circular concrete column, a fire resistance test was carried out for circular concrete column specimens. As a result, it was confirmed that PET fiber was effective against the spalling control of high strength concrete. However, the specimen with cover thickness 30mm did not satisfy the temperature standard of main reinforcement, and the specimen with cover thickness 40mm satisfied the temperature standard of main reinforcement. Therefore, more than 40mm cover thickness was demanded for stable fire resistance performance.
