Fire behaviour of FRP wrapped square reinforced concrete columns

Fibre-reinforced polymers (FRPs) have shown good performance in retrofitting and repairing deteriorated reinforced concrete structures, according to research and field applications. Due to a lack of information on the fire performance of these systems, an experimental and analytical study is being conducted on the fire behaviour of FRP-strengthened square reinforced concrete columns. The ultimate goal of the study is to provide design recommendations and guidelines for these structural members. This paper presents the explicit finite difference procedure used in developing a coupled heat transfer and structural analysis behaviour in numerical fire models. It also discusses the procedure for fire endurance tests on two FRP-strengthened square concrete columns, which will be performed in an attempt to validate the numerical models.
