Strengthening of concrete columns with carbon fiber-reinforced polymers (CFRPs) has become increasingly popular for civil infrastructure applications. The CFRPs has significantly enhanced the strength and ductility of concrete by forming perfect adhesive bond between concrete and the wrapping material. The objective of this study is to investigate the behavior of reactive powder concrete (RPC) short columns. Longitudinal reinforcement ratios of 0 and 4% were studied. Moreover, the influence of CFRPs wrapping layers including 0,1 and 2 was also investigated.In this regard, nine columns were tested up to failure, to study the effect of concrete type (normal concrete and RPC), presence of steel fibers, the shape of cross section (square and circular) and the CFRPs numbers of layers. Experimental data for strength, longitudinal and lateral strains and failure mode were obtained for each column. The numerical predictions are compared with the experimental data. The results of the RPC columns wrapped with CFRP showed stiffer behavior compared with RPC columns without CFRPs. Also, inclusion of steel fibers in RPC showed an effective way to prevent spalling of the concrete. Increasing number of CFRP layers enhanced the performance of the tested columns. 39.6% increase of the ultimate load carrying capacity was recorded for column cast with RPC containing 2% steel fiber volume fraction, reinforced with 4% longitudinal steel and wrapped with one layer of CFRPs over the control RPC column. Moreover, 80% increase of the ultimate load carrying capacity was noticed for normal concrete column wrapped with one layer of CFRPs over the unwrapped one of the normal concrete.
