“…In FIGURE 5 the deformed shapes near collapse provided by pushover analyses, with indication of the location of control points and the corresponding pushover curves (on the right) are also represented to give an idea of the active failure mechanisms and the amount of displacement reached by the different nodes monitored during the analyses. Only X-and Y-load cases are shown for the sake of conciseness, but it is interesting to notice that failure mechanisms are always local, a peculiar behavior for such kind of structures [2][3][4][5][6][7][8][9][10][11][12][13]. Similar results are found by the authors for the seismic load applied along the positive directions of the geometric axes (i.e.…”

“…A correct estimation of their load carrying capacity against horizontal loads should be therefore considered mandatory to guarantee their safeguard, allowing focusing restoration interventions on the base of quantitative information and on the expected structural behaviour in occasion of earthquakes. In the technical literature, several advanced numerical approaches are available for single case studies [2][3][4][5][6][7][8].…”

Santo Domingo church is analyzed as part of a broader research with the goal of reporting earthquake-resistant features in the masonry architectural heritage of the historic center of Santiago, Chile. Considering that Chile is one of the most seismic countries in the world, it is interesting how some historic buildings built between the XVI and the XVIII century still remain, despite construction with vulnerable building techniques such as unreinforced masonry. Among those buildings, Santo Domingo church is the only one built in stone ashlar and one of the few that has never suffered strong structural damages after earthquakes. Built between 1747 and 1771, this church has withstood around 11 earthquakes of magnitude over 7 without serious mechanical failures. Constructive and structural characteristics of Santo Domingo Church are assessed through historical research, field analysis and tests, damage assessments and finite element analysis. This analysis identifies early earthquake-resistant design criteria of the church, and determines vulnerable areas and their behavior during the last seismic events.Key words: earthquake-resistant features, Colonial heritage, historical buildings, constructive-structural analysis, seismic vulnerability. ResumenEl análisis de la iglesia de Santo Domingo forma parte de una investigación mayor, cuyo objetivo fue descubrir las estrategias de diseño sismorresistente presentes en el patrimonio arquitectónico construido en albañilería del centro histórico de Santiago. Considerando que Chile es uno de los países más sísmicos del mundo, es interesante constatar cómo algunos edificios históricos construidos entre los siglos XVI y XVIII aún existan, a pesar de haber sido construidos con técnicas vulnerables como lo son las albañilerías sin refuerzos. Entre aquellos edificios, la iglesia de Santo Domingo es la única construida en sillería de piedra y una de las pocas que nunca ha presentado daños estructurales severos durante los terremotos. La actual iglesia, construida entre 1747 y 1771, ha soportado alrededor de 11 terremotos sobre magnitud 7 sin presentar mecanismos de daño serios. A través de una investigación histórica, trabajo de campo y realización de ensayos, evaluación de daños y análisis de elementos finitos, las características constructivas y estructurales de la iglesia han sido determinadas. El análisis ha permitido identificar los tempranos criterios de diseño sismorresistente de la iglesia, así como determinar sus áreas vulnerables y su comportamiento durante los últimos eventos sísmicos.Palabras clave: características sismorresistentes, patrimonio colonial, edificios históricos, análisis constructivo-estructural, vulnerabilidad sísmica.

“…Chiostrini et al [23] combined the DP and the WW criteria to reproduce the results of several diagonal tests on masonry specimens, obtaining good agreement with experimental values. Betti and Vignoli combine the DP and the WW criteria to discuss the seismic vulnerability of a masonry church [15,30]. The cohesion c and the internal friction angle φ are the two material parameters required to define the DP yield surface.…”

“…Each iteration comprises a linear elastic analysis, so the procedure is useful for current design practice. Betti and Vignoli [15] discussed the seismic vulnerability of the Basilica of Santa Maria of Impruneta (Italy), and proposed the combination of a finite element model of the building with a simplified approach based on the kinematic theorem of limit analysis. The results suggest that the comparison between different techniques of analysis is mandatory to cover the unknowns affecting the mechanic properties of the materials.…”

Recent Italian earthquakes have underlined the need for wide monitoring and safety assessment of architectonical heritage. This has emerged also from requirements of the new Italian Technical Recommendations for buildings. Within this subject the paper investigates the seismic vulnerability of a specific monumental masonry building: the Vicarious Palace (Palazzo del Vicario) in Pescia, a small town near Florence. The structural behavior of the Palace was investigated using a finite element model in which the non-linearities of the masonry were considered by proper constitutive assumptions. The seismic behavior was evaluated by the pushover method, according to the Italian Technical Recommendations. The results were compared with the ones obtained by a simplified approach based on the kinematic theorem of limit analysis. Comparisons of the expected seismic demand vs the seismic capacity of the Palace confirm the weakness of this type of building to suffer extensive damage under earthquakes, as frequently observed in similar construction typologies. Additionally, the comprehension of the structural behavior under seismic loading allows the identification of a proper retrofitting strategy.
