The main objective of the work in this thesis is to study the Shear Behavior of self Compacting Concrete Slender Beams Strengthened With Carbon Fiber Reinforced Polymer Sheets.

The experimental work consists of fabrication and testing simply supported reinforced concrete self compacting concrete(SCC) beams , consists of five beams failed in Shear and each beam had 2100 mm length and (175x300)mm cross sectional dimensions, shear span/depth ratio (a/d) of (3)(Slender beam), all SCC beams made from self-compacting concrete with concrete compressive strength of about 45.894 MPa were casted and tested at 28 days.

This research is devoted to investigate the behavior and load carrying capacity of reinforced concrete strengthened and repaired with carbon fiber reinforced polymer (CFRP) sheets in Shear .
