Research on Peak Stress of CFRP Confined Concrete Columns under 2 Times Compression

Ma, Wei Hua

Three series compressive tests of concrete columns, CFRP constraint concrete columns and CFRP constraint concrete columns under compression are carried out to study the influence of initial stresses on strengthening effect. Through comparing the data of experiments, initial stresses’ influence on stress peak of 2 times compressive specimens is analyzed and the calculating formula of peak stress is proposed considering the pre-compression ratio, aiming at providing experimental dependences for strengthening design.
