Seismic Vulnerability Assessment of Historic Masonry

What is Seismic Vulnerability Assessment of Historic Masonry?
Seismic Vulnerability Assessment of Historic Masonry evaluates the susceptibility of unreinforced masonry structures in historic buildings to earthquake damage using kinematic limit analysis, nonlinear finite element modeling, and empirical vulnerability curves.
This subtopic catalogs failure mechanisms like out-of-plane overturning and in-plane shear in historic masonry. Methods include 3D micro-modeling (D’Altri et al., 2018, 180 citations) and stochastic approaches (Asteris et al., 2019, 106 citations). Over 10 key papers from 2005-2020 address computational modeling and case studies, with D’Altri et al. (2019, 491 citations) reviewing strategies.
Why It Matters
Vulnerability assessments prioritize retrofits for cultural heritage sites, as in the historic center of Coimbra (Vicente et al., 2010, 284 citations). They inform risk mitigation in seismic zones like Italy's Abruzzi region (Brando et al., 2017, 105 citations). D’Ayala (2005, 97 citations) provides force-displacement methods applied to traditional buildings worldwide, guiding preservation policies.
Key Research Challenges
Heterogeneous Material Modeling
Historic masonry exhibits nonlinear behavior and variability, complicating accurate FEM simulations. D’Altri et al. (2019, 491 citations) classify modeling strategies, noting challenges in capturing mortar joints. Validation against shaking table tests remains limited (Mendes, 2012).
Soil-Structure Interaction
Seismic response couples building dynamics with soil, as seen in the 2016 Italy earthquake case (Brunelli et al., 2020, 120 citations). Numerical models struggle with SSI nonlinearity. Ambient vibration testing aids but requires advanced calibration.
Scalable Vulnerability Curves
Deriving probabilistic curves for building typologies demands large datasets. Chieffo et al. (2019, 113 citations) compare fragility methods for Muccia, Italy, highlighting inconsistencies. Stochastic methods (Asteris et al., 2019) address uncertainty but need empirical validation.
