Exploring Deflection Characteristics of Externally Reinforced PCC Beams Using ANSYS: A Comparative Study of Bonded Steel Plate Applications with Different Grades of Concrete

The deflection characteristics of externally reinforced plain cement concrete (PCC) beams using ANSYS are studied, representing a significant exploration in civil engineering. The ultimate behaviour of PCC beams enhanced with external reinforcement is analyzed, with a particular focus on their deflection properties under varying loading conditions. After gaps in the literature are identified, objectives such as the selection of deflection parameters, the use of FEM modeling to assess behavior, and the application of steel plate retrofitting methods across different beam faces are outlined. The effects of different thicknesses of retrofitted steel plates and varying grades of concrete are examined, categorized into findings under Part A and Part B. Part A evaluates the impact of bonding steel plates, both with and without their application, while Part B compares results based on grade change criteria. Simulation results are analyzed, and conclusions are drawn, revealing that PCC beams perform optimally when reinforced with varying thicknesses of external steel plates alongside different concrete grades, resulting in reduced deflection under applied loads.
