Abstract

In the seismic strengthening of existing reinforced concrete bridge piers with use of carbon fiber shees (CFS), it is essential to evaluate the confinement effect of the concrete by the CFS. Since there must exist the lateral hoops in the columns, it is required to evaluate the interaction between the CFS and the hoop on the confinement effect. A series of uniaxial loading test was conducted for concrete cylinders confined by the hoops and the CFS. The interaction effect is analyzed based on the test results, and a stress-strain model of concrete confined by both CFS and the hoops is proposed.
