Axial Compressive Behavior of R/C Columns Confined with Carbon Fiber Sheets

탄소섬유쉬트로 횡구속된 RC기둥의 압축거동

External Confinement of concrete in CFS enhances strength and ductility of concrete columns. This paper presents the test results on the study of reinforced concrete columns strengthened with carbon fiber sheets. The purpose of this research is to evaluate the CFS confinement characteristics of square reinforced concrete columns and the CFS efficiency. The tests were performed with different lateral reinforcement ratios, CFS reinforcement ratios and concrete strength. Test results were characterized according to maximum loads and lateral strain of CFS.
