Abstract
Abstract
The use of Fiber-Reinforced Polymer (FRP) composites for strengthening reinforced concrete beams has gained widespread attention due to their high strength-to-weight ratio and corrosion resistance. This study provides a quantitative analysis of FRP strengthening by compiling and examining 580 datasets from existing experimental studies. The primary objectives include synthesizing experimental findings, identifying key factors influencing FRP performance, and evaluating the relative effectiveness of different FRP types, application methods, and beam geometries. Through systematic data collection and evaluation, the study assesses how variables such as FRP type, strengthening technique, and beam dimensions influence structural performance. The findings reveal that CFRP (Carbon Fiber-Reinforced Polymer) consistently enhances beam load capacity, while the Near-Surface Mounted (NSM) method demonstrates superior bonding and performance compared to the Externally Bonded (EB) technique. Additionally, beam depth and concrete strength significantly impact the efficiency of FRP strengthening, with deeper beams exhibiting a more pronounced size effect on shear capacity. The study contributes to a more structured understanding of FRP application in reinforced concrete strengthening by consolidating experimental data and highlighting the most effective strengthening strategies. The results offer valuable insights for engineers and researchers seeking to optimize FRP implementation in structural rehabilitation projects. These findings are particularly relevant to the Philippine construction industry, where effective strengthening solutions are essential for aging infrastructure.
