Abstract

This paper illustrates the finite element modeling of concrete columns with and without GFRP (Glass Fiber Reinforced Polymer) wraps. A series of Finite Element models were developed for pushover analysis. Two of them were built according to Iranian code (ABA) detailing and the rest of them according to ACI 318-Pre 71 detailing. Half of the models are assumed to be wrapped by FRP.The analysis was a displacement control analysis with a 5 cm displacement applied at the top of the column, with various ratios of axial load, from 0.05 Agf'c to 0.25 Agf'c. The analysis resulted in a force displacement capacity envelope of retrofitted and unretrofitted columns. Only parts of the bottom of the columns were wrapped up to the recommended splice length of the bars.It is shown that applying GFRP can increase the ductility, as well as the flexural strength, of the RIC columns. Also, a comparison between analytical and experimental results implies that the proposed modeling can be used with sufficient accuracy.
