“…The failure criteria define the elastic limit of a material subjected to a complex stress state [8,9,13]. The fundamental problem is to relate the critical parameters of the material obtained with simple uniaxial tests, with the resistance of the material subjected to multiaxial stress regimes.…”

“…Among the possible failure criteria present in the literature several works demonstrated that the Concrete Damaged Plasticity Model (CDP) is easily adaptable to all the material having brittle behaviour such as masonry, but these claims have hardly been validated by comparison with experimental tests on entire wall panels or entire masonry structures [4][5][6]. Another model which can be used for the definition of the macromechanical behaviour of the brittle anisotropic materials is the Drucker Prager (DP) [7][8][9][10][11] whose main lack is the loosing of accuracy in presence of large displacement as the model is not able to catch the variation of the cohesion as a function of the plastic deformation.…”

Sometimes it is difficult to choose the most appropriate failure criterion for the problem analyzed. For brittle materials, attention must be paid to the availability of experimental data and the calibration of the representative parameters, within the chosen failure criterion. The work herein presented, starting with an overview on machromechanical failure criteria, analysed in the Haigh-Westergaard Stress Space, investigates the suitability of Mohr-Coulomb, Drucker-Prager and Concrete Damaged Plasticity failure criteria of masonry structures, underlining their specific characteristics and implementation in FEM simulations. The Pavia Door Wall experimental campaign under pseudo-static cyclic test is considered as benchmark study. The results of the experimental tests are compared with a FE model developed with ABAQUS computer program considering several failure criteria and equivalent frame approach. Among the investigated failure criteria Concrete Damaged Plasticity is able to capture the actual behaviour of the masonry walls under monotonic excitation. In particular, thanks to the adaptability of the Guo’s model in the definition and calibration of the uniaxial behavior, the model suitability in catching the variation of the cohesion and the evolution of the damage is better in comparison with the other addressed failure criteria.

“…First, the number of different material models developed over the years and implemented in structural computer codes has raised concerns on the objectivity of the results obtained. As a consequence, the assessment of advanced numerical models has been become a topic of increasing interest in the scientific community [95,96]. Acknowledging the different hypotheses at the base of the models, and the selection of material parameters should be considered model-dependent [97], and appropriate tests should be carried out to estimate them.…”

The present manuscript deals with the seismic vulnerability assessment of existing masonry churches, which is a fundamental process for risk and consequent prioritization analyses, as well as application of effective retrofitting strategies. In the past, different approaches with various levels of accuracy and application ranges have been developed to assess the vulnerability to damage of such structures in case of seismic events. Based on the classification provided in the Italian Guidelines for the Cultural Heritage, in this paper a review of seismic vulnerability assessment methodologies for existing masonry churches is presented. The main goal of the current study is to provide a critical comparative overview about these procedures, highlighting the main issues related to the application of each detail level. Moreover, particular attention is focused on the applications present in literature, allowing for the definition of a potential systematic procedure for smart management policy aimed at preserving cultural, architectural and historical heritage.

“…Because of troubles in numerical modeling and excessive computation requirements, the micro-model is appropriate for small-scale simulations [11]. Therefore, homogenization techniques are addressed, in which it is not possible to distinguish masonry units and mortar joints from each other and masonry constructions can be modeled in an integrated manner [12,13]. The simpli ed macro modeling homogenized strategy is very promising in analyzing large-volume models and is applicable for the safety assessment of masonry constructions in engineering practice due to adequacy and computational e ciency.…”

Heritable constructions are an essential portion of the history of any nation in addition to nancial resources. The aim of this study is to investigate the earthquake damage and failure mechanism of a historic Bazaar located in Kashan (center of Iran), which dates to the seventeenth century. Numerical models were constructed by a macro method, considering two cases of xed support and soil-structure interaction (SSI). To assess the structural behavior, modal, nonlinear static and dynamic time history analyses were performed using a three dimensional nite element method. The results of SSI analysis show an intense weakness of the structure against the required demand based on the design spectrum. Also, foundation exibility has a great impact on the oscillation characteristics, displacement demand and damage distribution. By comparing the results of time history analysis to the pushover procedure, a lower shear value and higher displacement are obtained. Furthermore, the damage process is as dome collapse alongside short arc, consequently long arc collapse followed by pier wall overturning.
