Aiming to evaluate their structural response in a computationally efficient framework, machine learning metamodels, in the form of artificial neural networks, are adopted. Datasets are numerically built, integrating Matlab, Python and commercial finite element software. Heyman’s assumptions are adopted within non-linear finite element analysis, incorporating contact-friction laws between adjacent stones, to capture failure in the arch. The artificial neural networks are trained, validated, and tested using the least square minimization technique. It is shown that the proposed scheme can be used to provide a fast and accurate prediction of the deformed geometry, the collapse mechanism and the ultimate load. Cases studies demonstrate the efficiency of the method in random, new arch geometries. Relevant Matlab/Python scripts and datasets are provided. The method can be extended towards structural health monitoring and the concept of digital twin.Siphesihle Mpho Motsa has been supported by Erasmus + Program within the framework of action “International Credit Mobility” between the Technical University of Crete, School of Production Engineering and Management and the University of KwaZulu-Natal, department of Civil engineering under Structural Engineering & Computational Mechanics (SECM) Group.http://creativecommons.org/licenses/by/4.0/Engineering Structures296 Motsa Siphesihle Mpho Stavroulakis Georgios Σταυρουλακης Γεωργιος Drosopoulos Georgios Δροσοπουλος Γεωργιος Elsevier FEM Machine Learning Artificial Neural Network Multi-hinge failure Damage Prediction Masonry Arches Data-driven Mechanics Digital Twin
