Abstract

Over the past decade, research has shown that fiber reinforced polymers (FRP’s) can be efficiently, economically and safely be used for strengthening and rehabilitation of reinforced concrete RC structures. However little is known about the behaviour of FRP materials, at high temperature and this is a primary factor limiting the widespread application of FRP materials in buildings, parking garages and industrial structures. This paper presents the results of a numerical program to investigate the fire performance of FRP wrapped confined RC columns. The primary objective of this research paper is -: to develop numerical models to simulate the behavior in fire of these members; to investigate techniques to improve their behavior in fire; and to use data from numerical studies to provide fire design guidance. A numerical model is presented which is capable of predicting the thermal and structural response of FRP wrapped confined RC columns under exposure to standard fire.
