Structural Analysis of RCC Beam-Column Joints Strengthened with FRP using ANSYS: A Comprehensive Review

The drive for advanced solutions for the RCC beam–column joints which are performance improved has been among the reasons why more and more research and interventions are taking place in such tough areas of concrete strengthening and refurbishment. The work at the core of this paper, however, was not just to see through the adoption of the FRP system in such practices but it was also to provide the base for TRP as a good practice material for cement structures at the end of the road. The major target was to investigate the FRP retrofitting's effect on the load capacity, ductility, and stiffness of the structure, as well as to analyze the interaction of the FRP with the whole failure modes of those structural elements. For that reason, sophisticated finite element simulations were performed with the help of ANSYS to imitate the behavior of unstrengthened and strengthened (FRP) RCC components under different loadings. Survey results revealed that the efficacy of the FRP application is, to a large extent, responsible for the improved performance of the RCC joints and shear walls, with the factors of resistance to load and ductility being the most significant ones. Also, the performance of different FRP types - such as CFRP and GFRP - has been shown to offer different and sometimes overlapping benefits depending on the situation. The corresponding comparison, supported by laboratory trials, validates the simulation results and shows the realworld impact of using FRP in concrete retrofitting. The whole study has emphasized the need of the FRP in the infrastructure's ability to handle catastrophes and has contributed necessary guidance for future advancements in civil engineering materials and methods of strengthening.
