Performance in fire of fibre reinforced polymer strengthened concrete beams and columns: recent recent and implications for design

Abstract

This paper considers the fire performance of concrete beams and columns that have been strengthened with fibre reinforced polymers (FRPs). Results from four recent full-scale tests are presented. A newly developed type of insultation was employed and the thickness of the insulation (15 to 20 mm) was approximately half that provided in earlier tests. All of the members survived four hours of fire exposure. A conceptual model for design is also presented. Further research needed to fully develop the conceptual model to a more practical design tool is outlined.Peer reviewed: YesNRC publication: Ye
