Abstract
Interest in the use of fiber-reinforced polymers (FRPs) in civil engineering applications has increased significantly in recent years. FRPs offer advantages, such as high strength and corrosion resistance over traditional materials such as concrete and steel. FRPs have been successfully used both as internal reinforcement and as externally-bonded reinforcement for reinforced concrete (RC) structures. As an external reinforcement, the use of FRP sheets or plates is now a method of choice for the rehabilitation and strengthening of concrete members in many cases. In these applications, FRPs are commonly wrapped around columns to increase their strength and ductility, or bonded to beams to improve flexure and/or shear capacity, slabs to improve flexural or punching capacity, or to strengthen structural connections. At present, the use of FRPs is restricted primarily to bridge structures, where fire resistance is not a primary design consideration. However, there is enormous potential for the use of FRPs in buildings. Structural building members must be designed to satisfy appropriate fire resistance requirements in addition to other structural requirements specified in building codes. One of the main impediments to using FRPs in buildings is the lack of knowledge about the fire resistance of these systems. Before FRPs can be used with confidence in buildings, the performance of these materials under fire conditions, and the ability of structural members with which they are reinforced or strengthened to meet the fire resistance criteria set out in building codes, must be evaluated.
