TL;DR: In this paper, the authors present the solutions adopted for the implementation of the equivalent frame model in the TREMURI program for the nonlinear seismic analysis of masonry buildings, which is also expressly recommended in several national and international codes.

TL;DR: A comprehensive review of the existing modeling strategies for masonry structures, as well as a novel classification of these strategies are presented, which attempts to make some order on the wide scientific production on this field.

TL;DR: In this article, a displacement-based approach is adopted, because these structures crack even for low intensity earthquakes and can survive severe ones only if they have a sufficient displacement capacity, which is the main cause of damage for ancient masonry structures and is necessary to have accurate models for the seismic analysis, able to simulate the nonlinear behavior of masonry, and a well defined performance-based assessment procedure, aimed to guarantee the acceptable level of risk for the occupants and for the conservation of the monument itself.

TL;DR: In this paper, the authors investigated the specific vulnerability factors and construction features of unreinforced masonry buildings in the affected area, in particular in the area between Amatrice and Arquata del Tronto.

TL;DR: In this article, a critical review of the most widespread strength criteria present in the literature and codes to interpret the failure modes of piers (rocking, crushing, bed joint sliding or diagonal cracking) are proposed.
