Abstract

The repairing technique of surface wrapping concrete structural members using fiber composite sheet have been widely used. The research efforts have been limited to studying relative strength increase of repaired concrete structures rather than ductility improvement based on composite material effect and the interface effect between composite and concrete. The compression tests of CFS(carbon fiber sheet) reinforced concrete specimens with various cross-sectional shapes and laminate angles have been peformed. FEM algorithm considering various parameters will be performed based on the obtained data. The results will be discussed in detail.
