چکیده انگلیسی
Repair and strengthening of reinforced concrete (RC) members in existing structures are very important to extend their service life. In this study, steel fiber reinforced high strength lightweight self-compacting concrete (SHLSCC) developed by the authors is applied for the strengthening of RC beams to improve their bending moment capacities. There are significant improvements in stiffness of strengthened beams as well as 14 - 58% improvements in peak load when strengthened with 40Â mm, 50Â mm and 60Â mm layers of SHLSCC. Application of SHLSCC in lower half (tension zone) of the beam increased its peak load by 33.1%. Results indicate that the material may effectively be utilized for strengthening of bending members in existing structures.
