NUMERICAL VALIDATION OF MASONRY WALL EXPERIMENTS USING THE APPLIED ELEMENT METHOD

This study presents a numerical validation of experimental results on masonry wallets using the Applied Element Method (AEM). Due to their historical nature, masonry structures are highly relevant in modern construction; however, they normally pose certain challenges regarding structural analysis because of their composite nature and nonlinear behaviour. While experimental investigations provide critical information, numerical modelling is a very efficient way to extend the knowledge regarding masonry performance under different loading conditions. In this research, the Applied Element Method, a relatively new analysis method was employed. The method bridges the gap between continuum and discrete element approaches. AEM's ability to model crack initiation and propagation makes it particularly suitable for analysing the complex failure mechanisms detected in masonry structures. A series of tests were carried out on both unreinforced and strengthened solid brick masonry wallets under different loading conditions. Preliminary results indicate good agreement between the AEM simulations and experimental results, particularly in terms of predicting the nonlinear response and failure modes of masonry wallets. This study highlights the potential of AEM as a powerful tool to understand and predict the complex response of masonry structures, which has important implications for both the conservation of historic buildings and modern masonry design.
