Abstract

Over the past decade, the use of fiber-reinforced polymers (FRPs) as bonding agents to enhance and rehabilitate concrete structures has become widespread. Despite the demonstrated effectiveness of this approach in numerous experimental studies, there are still concerns about the time and expense required for these investigations. To address this issue, The objective of this study was to investigate how the carbon fiber-reinforced polymer (CFRP) reinforcement affects the bending performance of one-way reinforced concrete slabs using advanced finite element software (ABAQUS). To investigate the impact of various factors on slab performance, two models of one-way RC slabs were developed, taking into account concrete grade, number of CFRP layers, and opening size (600x600mm). By comparing the results obtained in this study with existing experimental data, the findings indicated that the approach adopted in this research could offer a cost-effective and efficient way to evaluate the performance of FRP-strengthened concrete structures.
