According to the experiment of 11 eccentrically compressed reinforced concrete columns and 1 comparative column under the monotonic loading, the bearing capacity，ductility，and the destruction mode of the columns before and after their consolidation have been compared and analyzed．The experimental results illustrates that external coherence of FRP could effectively enhance their bearing capacity and the improvements have relation to many aspects, such as the number of fiber layers, the category of fiber, approaches of how fiber sheet paste, the width of FRP and consolidation space and so on; the ductility of consolidation column mainly depends on how fabric pasted. Longitudinal pasting fiber sheets can greatly improve the bearing capacity of the column, but its ductility declined; the longitudinal-horizontal pasting fiber sheets can enhance column’s the bearing capacity and ductility and this brings about the best consolidation effects. Additionally, based on the analysis of experimental results, a formula for the bearing capacity of the normal section of the large eccentric loading reinforced concrete column consolidated with FRP sheets has been proposed, and the calculation results tally with the experimental results.
