Enhancing Rolled Steel I Beam Performance Through FRP Strengthening: Analytical and Numerical Modelling for Behavior Prediction

The results of this study add to the body of knowledge in structural engineering and offer a solid basis for the design of rolled steel I beams strengthened with fiber reinforcing polymers. Engineers and researchers can leverage the analytical and numerical models developed in this study to optimize the performance of structures subjected to varying loads, ultimately leading to safer and more resilient constructions.This research paper delves into the realm of structural engineering by investigating the efficacy of Fiber Reinforced Polymer (FRP) materials in enhancing the strength and performance of rolled steel I beams. The study presents a comprehensive analysis that combines both analytical and numerical modeling approaches to predict the way that FRP-strengthened I beams respond to loads. Analytical models are developed to establish fundamental relationships between material properties, beam geometry, and load distribution. In tandem with the analytical framework, numerical simulations are conducted using advanced computational tools. Finite Element Analysis techniques are employed to simulate real-world scenarios and validate the predictions from the analytical models. The numerical simulations offer a more intricate representation of the beam’s behavior, accounting for complex factors such as material nonlinearity and load eccentricities. The results in the creation of more robust and affordable structural solutions, which could help a variety of various infrastructure projects. For calculation of solution Matlab software is used for axial loading bending stress with boundary condition. Through a comparative analysis of the analytical and numerical results, this study provides insightful information about the accuracy and reliability of each modeling approach.
