Behaviors of concrete columns strengthened by CFRP sheets under eccentric compression

Cao Shuangyin Jing Denghu Sun Ning(Southeast University,Nanjing 210096,China)  
An experimental study of eccentrically loaded concrete columns confined by CFRP sheets is presented.The behaviors investigated in the test of five concrete columns reinforced by CFRP sheets include the ultimate strength,the lateral deflection,and the sectional strain distribution of concrete columns and transverse strains in the CFRP sheets.It is found that,via the reinforcement of CFRP sheets,the ultimate strength of concrete columns is enhanced and the ductility of concrete columns improved.The efficiency of reinforcement increases when the eccentricity decreases.It is also shown that the plane strain condition remains valid,i.e.,strain in concrete is linearly proportional to the distance from the natural axis.The strain gradient in CFRP sheet,which is attributed to the non-uniform expansion of concrete,is observed.A formula is proposed for calculating the ultimate strength of eccentrically loaded concrete columns strengthened by CFRP sheets,including the modified equivalent rectangular stress block and the limit value of the relative depth of the compression zone.
