| Abstract: | Basing on the experiment of 23 prototype reinforced concrete columns under eccentric simple-loaded action,four influence factors on the strength capacity and ductility of the columns have been studied respectively,which are the CFRP bond manner,load eccentricity,concrete strength and the longitudinal reinforcement ratio of columns.The research is significant to the strengthening of the RC columns with CFRP sheets. |

| Keywords: | carbon fiber-reinforced polymer/plastic(CFRP) eccentrically loaded reinforced concrete column strengthen bearing capacity ductility |
