This paper numerically investigates the flexural response of concrete beams reinforced with steel and four types Fiber-Reinforced Polymers (FRP), i.e., Carbon FRP (CFRP), Glass (GFRP), Aramid (AFRP), Basalt (BFRP). The responses forty two boundary conditions (simply supported over-hanging beams) were determined using ABAQUS. Subsequently, finite element models validated experimental results. Ev...

Abstract Lightweight concrete (LWC) is one of the most important building materials nowadays. Many research studies were focused on LWC produced using lightweight aggregates. However, limited work was cited for polystyrene beads. In this study, beams strengthened with carbon fibre reinforced polymer (CFRP) and glass (GFRP) experimentally tested to investigate improvement in their flexural shear...

Abstract The FRP material plays a major role as strengthening in RC structural elements. It is popularly used to improve the load carrying capacity and stiffness elements by wrapping with sheets (combination of GFRP & CFRP). usefulness laminates external at both sides full vertical strips interval 100mm on beams studied.. In this experimental study nine reinforced concrete were cast that th...

Corrosion of steel reinforcement is the major cause deterioration in reinforced concrete structures. Strengthening structures has been widely studied. However, most research was conducted on sound without considering effects corrosion. This paper presents an experimental study feasibility using externally bonded FRP laminates combined with U-jackets, applied directly repairing deteriorated cove...

Environmental awareness and the need for sustainable construction inspired researchers practitioners to explore innovative alternatives that might reduce greenhouse gas emissions energy use related excessive structural work. One such alternative is utilization of Fiber-Reinforced Polymer (FRP) bars as a reinforcement in reinforced concrete members. FRP possess favorable characteristics like hig...
