“…Briccola and Bruggi [8] was presented a numerical approach to perform the equilibrium of three-dimensional linear elastic masonry-like structures exploiting the application programming interface of a general purpose software package that performs finite element analysis. In addition, there are various publications on historical bridges [9][10], historical churches [11][12], historical mosque, minarets and towers [13][14][15].…”

Historical masonry structures that connecting the past to the present have great importance because they represent the experiences and characteristics of various cultures. Therefore, the protection of historical structures is important. In this study, the structural response of the historical masonry Mosque was evaluated through dynamic analyses. For this purpose, the Sütlü Minaret Mosque which is located in Malatya, Turkey, was investigated. The three-dimensional model of the historical mosque was generated with ANSYS software. The material properties of the mosque were obtained with experimental tests. The time history analyses were used to obtain the seismic behavior of masonry mosque. In the time history analyses, six different strong ground motion records, including the 2020 Elazığ earthquake, were used. After the analysis, displacement and stress values in the mosque were given. The absolute peak displacement value among these earthquake records was obtained from the 1999 Düzce earthquake and the highest principal compressive and tensile stress values were determined for the 2010 Darfield earthquake. Also, the crack regions which occurred in the mosque after the 2020 Elazığ earthquake were compared with the dynamic analysis result of the 2020 Elazığ earthquake. The crack regions formed after the Elazığ earthquake are similar to the possible crack regions formed after the dynamic analysis.

“…These structures often have complex geometry that cannot be simplified with the conventional models, such as equivalent frames. The currently most adopted approach is the macro-modeling one with the Finite Element Method (FEM), where their geometry is accurately reproduced and discretized with 3D elements [3][4][5][6]. In the FEM the material is considered isotropic and homogeneous, and the nonlinear behaviour is simulated with Total Strain Crack (TSC) [7] or Concrete Damage Plasticity (CDP) [8,9] models.…”

The Cultural heritage spread all over the World needs to be preserved with systems that do not compromise its architectural and historical value. Nowadays, the most advanced technology available is the ambient vibration test. It allows to obtain the current frequencies, modal shapes, and damping of structures, without being invasive. The comparison between different monitoring campaigns and their use in combination with Finite Element models can give an insight into the state of structures’ health. This paper presents two ambient vibration tests performed on a fortified masonry tower in the Marche region of Italy, carried out after one year each other, with different temperature and humidity conditions. To extract the structure’s dynamic parameters both a time and a frequency domain approaches were used. The comparison between the parameters obtained during the two experimental campaigns showed similar frequencies and modal shapes underlining that no damage occurred and that the dynamic response of the tower does not suffer temperature and humidity variations. In addition, the steps carried out for a first attempt manual calibration of the tower’s Finite Element model are shown. The match between the numerical model and the experimental data is evaluated through the absolute frequencies’ errors and the Modal Assurance Criteria between the modal vectors. The calibrated numerical model can be used for future and accurate assessment of the tower’s structural capacity.

“…Accordingly, the first two approaches mentioned are receiving increasing interest from the scientific community, as evidenced by the large number of scientific works on several case studies. Three-dimensional non-linear finite element analyses of masonry churches are presented in [21][22][23][24][25][26][27][28]. In [29], push over analyses of ancient masonry churches described by three-dimensional discrete element models are developed.…”

Two Steps Procedure for the Finite Elements Seismic Analysis of the Casamari Gothic Church

et al. 2022

The structural analysis of historic masonry churches subject to earthquakes is commonly based on two distinct approaches: that of the global response to seismic actions and that of the local analysis of a priori pre-determined collapse mechanisms. This is a conventional decoupling of the structural problem due to the difficulty of addressing the seismic vulnerability of individual parts from the modelling of the whole. The aim of this work is to establish a link between the global behavior of the church and the assessment of the local mechanisms, re-evaluating the value of modal analysis to be associated with non-linear seismic assessment. With this aim, a two steps procedure is proposed, where: the first step is based on the detection of the main vibration modes of the whole building with identification of the structural bi-dimensional macro-elements that are responsible for the overall seismic vulnerability, while the second step, is based on the non-linear finite element analysis of the previously identified macro-elements, to evaluate the failure pattern caused by the earthquakes. The procedure will applied to the case study of the Casamari Gothic church in Veroli (Italy).
