| Abstract | ||
| The most current used technology for strengthening reinforced concrete (RC) beams is aluminum plate (AP). The use of AP to strengthen RC beams was investigated in this study. The experimental program included twenty-five RC beams (1/5 scale), with 14 and 11 beams strengthened in shear and flexure, respectively. All beams were the same size. All beams were subjected to four-point bending flexural tests. Various AP-based strengthening approaches were used. To improve shear strength, APs were glued vertically, inclined by 450 degrees, diagonally, and horizontally on the beams' sides (SS). The effect of AP pitch, height, and amount was investigated. APs of varying length, number, and pitch were agglutinated at the beam soffits to improve flexure strength (FS). All APs improved shear and flexure capabilities, while some of them modified the failure mode.
