Abstract |
This study evaluated fire resistance performance for hybrid (polypropylene + steel) fiber reinforced high strength concrete column. Full-size columns were constructed and tested with or without fibers using ISO-834 fire curve. As the result of test, Control specimen occurred serious spalling and indicated rapidly internal temperature increasing. Specimen with polypropylene fiber occurred not spalling but steady internal temperature increasing. Specimen with hybrid fiber occurred not spalling as well as does not propagated temperature distribution. Therefore, hybrid fiber reinforced column specimen indicated a good fire resistance performance than other cases.
