Shear Strengthening by Ductile Fiber Reinforced Cementitious Composite Jacketing

Present study focuses on verifying shear strengthening effect by DFRCC jacketing around existing members. In this study, a series of experimental tests have been conducted followed by Finite Element nonlinear analyses. It is concluded as following; 1) Horizontal cracks dominate in the DFRCC jacketed section independently with existing member with diagonal shear crack in which no particular bond treatment between existing and jacketing surfaces, 2) FE nonlinear analyses can predict experimental results up to the ultimate, 3) DFRCC shear strengthening effect can be predicted by the JSCE formula with considering the tensile strength of DFRCC.
