Numerical block-based simulation of rocking structures using a novel universal viscous damping model

G Vlachakis, AI Giouvanidis, A Mehrotra… - Journal of Engineering …, 2021 - ascelibrary.org
Unreinforced masonry structures, particularly façade walls, are seismically vulnerable due to
their weak connections with adjacent walls, floors, and/or roofs. During an earthquake, such …

Numerical procedures for the analysis of collapse mechanisms of masonry structures using discrete element modelling

F Gobbin, G de Felice, JV Lemos - Engineering Structures, 2021 - Elsevier
Earthquake damage in historic masonry buildings is generally caused by the collapse of
