“…Therefore, consideration of the uncertainties in the material properties is an important step towards the probabilistic performance-based assessment of masonry structures. As an example, probabilistic seismic assessment of masonry structures, including the uncertainty in the material properties, has recently been explored by a few researchers [54][55][56][57][58]. However, there is still a substantial need for research to quantify the uncertainties in the analysis, both at component and system levels.…”

“…In this section, the procedure established in this paper is to examine the probability failure and its corresponding RI ( ) of the minaret under earthquake action presented. The load-resistance (L-R) method utilized in structural reliability assessment in many researches [21,22,[28][29][30][31][32][33][34], also used in the present study. A normal distribution function N(µ, σ) is chosen to define the statistical properties of random variables (RVs).…”

Historical brick minarets are the main elements of Iranian architecture and exist throughout Iran in different dimensions and heights. In this paper, the structural behavior of the Gaskar brick minaret, in the north of Iran, with a height of 16.11 m, has been studied against wind and earthquake hazards. Accurate discretization of finite element (FE) model of the minaret is performed to achieve accurate structural results. Then the wind load (WL) and earthquake load demand are determined according to the national building regulations, and technical literature then applied to the structure. Macro modeling strategies were utilized to modeling the masonry materials environment. Nonlinear properties are also assigned to masonry materials. The equivalent static WL is considered according to national building regulations. Three strong ground motion earthquake records are considered as seismic loading. In order to probabilistic seismic safety analysis of minaret, the load-resistance method was used for reliability analysis. The elasticity modulus, tensile and compressive strength of materials used as random variables generated by Monte-Carlo simulation (MCS) for 10% coefficient of variations. Peak displacement response (PDR) of the minaret as implicit limit state (LS) function is determined under far-field ground motions. The seismic reliability index (RI) is quantified using the design of experiment (DOE) due to its time-consuming computational costs. The results showed that the minaret is safe against design WL and loading of the strongest wind recorded in the world. The seismic reliability results indicate that the minaret is at risk of slight damage.

“…Alternatively, sophisticated numerical models demanding a careful characterization of the material are required to simulate seismic behavior more efficiently. Discrete element modeling [16][17][18][19][20][21], finite element macro modeling [22], and finite element micro modeling [23] are versatile tools utilized for the nonlinear dynamic and static analysis of masonry arch bridges [24]. Researchers apply zero-thickness line interfaces in finite element micro-modeling and pointcontact elements for discrete element modeling approaches.…”

“…Turkey has a rich cultural heritage in historical construction as Anatolia hosted many different civilizations throughout history. A total of 1646 historical bridges attributed to the Hittites (1), the Romans (128), the Byzantines (22), the Seljuks (150), the Ottoman Empire (1280), and the early Turkish Republic (64) were documented in Turkey (numbers in parentheses indicate bridges associated to each civilization) [1]. Two examples of dry-joint masonry bridges in Turkey built during the Roman and Byzantine eras are illustrated in Figure 1.…”

The seismic performance assessment of dry-joint masonry arches is challenging because of their unique structural characteristics. Widely used assessment methods developed for frame-type structures require the use of a material-dependent section response. In contrast, the response of a dry-joint arch is not dependent on the material capacity but characterized by the sustainment of stability, primarily depending on rigid body rotation or sliding motion at the interfaces between the adjacent voussoirs. A hybrid methodology, combining a simple finite element micro model with principles of limit analysis method, is proposed in this work for the seismic performance assessment of these structures. The nonlinearity is concentrated at interfaces of the model by means of shear and compression-only axial springs. Kinematic conditions yielding a possible collapse mechanism were traced at every step of the time history analysis by checking the failure of individual interfaces. The procedure is applied to an ancient dry-joint Roman arch bridge in close proximity to the North Anatolian fault subject to significant seismic risk. Along with the performance of the system in its current state, the effects of retrofitting measures were investigated in the scope of this study.
