Abstract

The flexural strengthening effect of the RC beam strengthened with CFS under pre-loading condition was studied here. The beams were additionally strengthened at the each end with U type wrapping using the same CFS. Main variables considered were number of CFS plies(1,2) and pre-loading values(30,50,$70\%$ of the yield load of the control beam). The flexural strengthening effect was investigated through comparing the yield load, ultimate load, and ductility index of the specimens.
