Abstract: The use of aluminium plates (APs) as shear reinforcement in concrete beams was explored, with the aim of enhancing structural performance while benefiting from aluminium's corrosion resistance and lower weight compared with steel. An experimental and numerical investigation was conducted on various AP configurations (L-shaped, T-shaped, U-shaped and I-shaped) embedded in concrete, along with different bonding methods, including bolting and the use of specially designed openings to improve interaction with the concrete. The primary objectives were to assess the influence of the different configurations on shear capacity and ductility, compare bonding techniques and develop a validated finite-element model for accurately predicting shear behaviour. By integrating physical testing and advanced simulations, the objective was to optimise AP reinforcement designs for improved shear performance. It is hoped that the findings of this study will advance the application of composite materials in structural engineering, thus supporting the development of more efficient, durable and high-performance concrete systems.
