A MODEL FOR CONFINEMENT EFFECT FOR CONCRETE CYLINDERS CONFINED BY CARBON FIBER SHEETS

Most reinforced concrete bridge piers which suffered damage in the 1995 Hyogoken-Nanbu Earthquake were designed with the seismic standards of the 1960s in which the importance of ductility of structural components was not considered. Consequently, existing reinforced concrete columns which were designed with the seismic standards of the 1960s and are vulnerable to seismic disturbance require strengthening urgently. As one of the seismic strengthening methods of reinforced concrete columns, carbon fiber sheet (CFS) jacketing is an attractive method because of its superior workability. To reflect the confinement effects by the CFS in seismic strengthening, a series of compressive loading tests of concrete cylinders were conducted and a stress-strain model of concrete confined by CFS is proposed.
