“…These three safety indexes are applied on two databases including several churches in [26], providing results highly influenced by the buildings geometry and construction details. Also, in [27], the buildings architectural features are of great importance to investigate the seismic vulnerability and risk and to program interventions following a priority scale. Instead, in [28], the seismic vulnerability on large scale of masonry building aggregates is evaluated through a speedy procedure supported by the finite element method.…”

Recovering and preserving ancient churches is necessary to ensure the transmission of this cultural heritage to the future generations. To this scope, it is necessary to evaluate their performance in seismic prone areas, to design interventions capable of reducing their vulnerability ensuring also their safety use for the faithful. In this paper, investigations on seismic performance of masonry churches are illustrated by applying two different numerical methods on a case study, an existing brick masonry church. The seismic assessment is conducted by applying two simplified methods proposed by the current Italian Directive containing the Guidelines for assessment and reduction of cultural heritage seismic risk. Moreover, linear kinematic analysis is used also for investigating the influence of main parameters governing to the main façade simple overturning and narthex longitudinal response. The investigations performed highlight that the activation multiplier of macro-element response mechanism may significantly vary according to the assumptions made and that also, as narthex longitudinal response, a minimization procedure of the activation multiplier is required.

“…For these mechanisms, there is a wealth of literature references aimed at calculating the ultimate load factors by means of limit analysis, especially with kinematic approaches considering frictional behaviour [3][4][5][6][7][8][9][10][11][12]. In the last few decades, researchers have also developed analytical methods in the field of finite element (FE) analyses to examine ordinary masonry constructions [13][14][15][16][17] or have implemented large scale and detailed numerical investigations to study monumental constructions like churches [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33].…”

Local collapse mechanisms related to the out-of-plane response of walls are commonly observed in existing masonry buildings subjected to earthquakes. In such structures, the lack of proper connections among orthogonal walls and between walls and floors does not allow a global box-type behaviour of the building to develop, which would be governed by the in-plane response of walls. In this paper, parametric linear kinematic analyses on the main local mechanisms of masonry churches were performed with the aim to evaluate the corresponding horizontal load multipliers. This study was conducted on 12 masonry churches, located in Teramo (Italy) and affected by the 2016 Central Italy earthquake, whose main out-of-plane collapse mechanisms, namely facade overturning, vertical bending, corner overturning and roof gable wall overturning, have been analysed. For each mechanism, parametric analysis was carried out on varying heights and thicknesses of walls. Firstly, the acceleration values activating the considered mechanisms were calculated in order to conduct checks prescribed by the current Italian standard. Subsequently, on the basis of the obtained results, simple analytical procedures to determine load collapse multiplier for each mechanism were drawn. Finally, ranges of suitable values of both the thickness and height of walls were found in order to always satisfy seismic checks.

“…From a conceptual point of view, the LV1 procedure is particularly devoted to a territorial scale evaluation by the means of the estimation of a global vulnerability index for assessing the seismic performance. This approach strategy has been adopted also in other studies such as, for example, Lourenço and Roque (2006), Lourenço et al (2013), Formisano, Ciccone, andMele (2017), Formisano, Florio, Landolfo, & Mazzolani, September (2011), Valente & Milani (2018), and Marotta, Sorrentino, Liberatore, & Ingham (2018).…”

Nowadays, safety assessment under seismic loading of historical masonry buildings, such as ancient churches, is an actual and important topic due to the potential human and economic losses involved even for a partial collapse. Therefore, the prevention and mitigation of their seismic risk would result the best intervention for preserving in the future these monuments of inestimable value. To date, in literature many methods are available for evaluating the seismic vulnerability and the related risk. In particular, this study focuses on the first two simplified evaluation methods proposed by the current Italian directive containing the guide lines for assessment and reduction of cultural heritage seismic risk. The methods, having an increasing precision level, may be applied in sequence at a different scale for screening and identifying the present priorities, and for designing the required interventions. In this article, these methods are applied to five ancient masonry churches located within the UNESCO site of the "Sassi" of Matera (Italy), a seismic-prone area with moderate seismicity. Afterward, also a new simplified method is applied, in the form of fast appraisal method useful for preliminary ranking the seismic performances of the case studies at a territorial scale.
