Abstract


Reinforced concrete and steel plates are widely used in civil engineering and are important components of many structural systems and ground reinforcement projects. These plates effectively carry different loads, enhance ground support, and improve the durability of structures. Moreover, the proper selection and use of these materials during the design and planning stages of construction projects have a direct impact on cost and time efficiency. In addition to their structural contributions, the effective use of reinforced concrete and steel plates is critical for the safety and success of construction projects. In order to transfer loads to the frame system, reinforced concrete plates serve as horizontal load-carrying components. Load-bearing capacity, stiffness, fire resistance, and sound insulation are important properties of reinforced concrete plates. Perforated plates are widely used in structural applications but suffer from stress concentration around openings, reducing their mechanical performance. This study investigates the reinforcement of perforated steel plates using fiber-reinforced polymer (FRP) composites around holes to enhance structural integrity. The research employs finite element analysis (FEA) to assess the effects of different reinforcement widths under varying loads. A detailed comparison of stress and deformation distributions before and after reinforcement is presented. The findings indicate that FRP reinforcement significantly reduces stress concentration and improves the load-bearing capacity of perforated plates, providing practical insights for industrial and construction applications.
