Material aging effects on the in-plane lateral capacity of tuff stone masonry walls: a numerical investigation

Abstract Recent studies have shown how the variability of material properties affects nonlinear behaviour unreinforced masonry (URM) walls. To preserve historical built heritage, variations in structural capacity URM buildings associated to aging and deterioration should be quickly predicted, by integrating with health monitoring risk management. In this study, relationships between features are numerically investigated for single walls, based on a modelling strategy that was experimentally validated full-scale The paper proposes an evaluation effects degradation macroscopic descriptors such as peak strength stiffness, also considering uncertainties estimate those properties. authors do not attempt model physical processes time, but assume certain levels investigate their response capacity. Force–displacement curves failure modes overall walls due progressive Regression models then proposed predict load-bearing -plane lateral stiffness when mechanical constituents changed.
