Abstract

Concrete structures are vital components of modern infrastructure due to their strength and durability. However, over time, these structures are susceptible to various forms of deterioration, including cracking, spalling, and weakening, often resulting from factors such as moisture, chemicals, and seismic events. The need for effective repair and strengthening methods, particularly in earthquake-prone regions, has led to the widespread adoption of Fibre Reinforced Polymer (FRP) composite fabric as a solution.
This dissertation explores the application of CFRP for repairing and recovering damaged concrete structures through advanced modelling and analysis. Leveraging Finite Element Analysis (FEA) in LUSAS software, the research investigates the structural performance of damaged concrete beams repaired with CFRP under various loading conditions. Specifically, the study examines to get the optimized solution of the wrapping sheet, the influence of CFRP dimensions, such as length, and fibre direction, on structural repair effectiveness.
The methodology involves the design and modelling of concrete beam samples with varying CFRP configurations, including different lengths, and different number of layers with different fibre directions. Through detailed numerical simulations, the study aims to optimize CFRP application to achieve the most effective repair outcomes. Additionally, the research addresses a significant research gap by systematically determining the optimum dimensions of CFRP materials.
The findings of this dissertation contribute valuable insights to the field of structural engineering and construction materials. By providing practical guidelines and recommendations for engineers and practitioners involved in structural rehabilitation, the research aims to influence industry practices and construction standards. Ultimately, this dissertation strives to offer cost-effective and durable solutions for repairing and recovering damaged concrete structures, thereby enhancing their resilience and extending their service life.
