The aim of this study was to evaluate shear performances of reinforced concrete beams retrofitted by using wire mesh and Self Compacting Concrete (SCC). Four concrete beams reinforced internally with steel and externally with both wire mesh (??4,06mm) and SCC (25mm) applied to the specimens were tested under three-point bending. The shear failure was initiated by a major diagonal crack within the beam shear span. This diagonal crack extended horizontally at the level of the wire mesh. Results show that SCC with wire mesh is very effective for shear retrofitting. Increases in shear capacity of 71.82% for BWS over the BN as control, un-retrofitted beams were noted. |
