The current research is dedicated to studying the flexural behavior of composite box beams with corroded bottom flanges. Six simply supported beam specimens were manufactured and tested. fabricated steel 1100mm, 100mm, 100mm for length, width, height, respectively, while concrete deck slabs made dimensions 400mm, 50mm thickness, respectively. sections formed by connecting RC using a headed shea...

In most cases, openings are made in the Web of deep beams for installations to pass through. These members require be strengthened since reduce load-bearing capacity. This study utilizes carbon fiber-reinforced polymer (CFRP) composites and steel protective frames (SPF) as strengthening configurations reinforced concrete (RC) improve strength lost due square openings. To this end, eleven specim...

It is an effective way to improve the flexural behavior of reinforced concrete (RC) members by externally bonded carbon fiber reinforcement polymer (CFRP) laminates on the soffit of the members. However, there is little investigation on flexural performance of RC beam flexurally strengthened by side-bonded FRP laminates. To investigate the flexural behavior of RC beams side-bonded CFRP laminate...

Abstract In reinforced concrete (RC) structures, corbels that extend from the faces of columns are commonly employed to support primary beams and girders. Frequently, use is limited cantilevers with a shear span-depth ratio often less than 2. Because this relatively low ratio, corbel strength normally dominated by shear, which comparable deep beams. However, owing some reasons (e.g., design and...
