Laminated and pasting CFRP composite strengthening RC beam bending bearing capacity experimental study

LI Hongxia1,GUO Yanqin1,ZHANG Leishun2(1.Huanghe Science and Technology College,Zhengzhou 450063,China; 2.Zhengzhou University,Zhengzhou 450000,China)  
Through the analysis of laminated composite of RC beams strengthened with bonded CFRP bearing force of the two major influencing factors,using the existing calculation method of composite strengthening RC beam is derived the formula to calculate the bending bearing capacity,test found that:only paste CFRP strengthened RC beams,can effectively improve the bearing capacity of members,but due to the lower tensile reserves and the upper compression reserve is relatively insufficient,make a component similar over-reinforced beam brittle failure,its ultimate bearing capacity was significantly lower than the upper part while the laminated layer of RC beam.Test comparison showed that:this method calculated value compared with experiment data is small,conservative calculation formula.
