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.

“…The acceleration component with a maximum value of 373.7 cm/s 2 is applied in the minaret's horizontal (x) direction. Many researchers have used the effective portion of acceleration records instead of a full record [20,33,[43][44][45][46][47]. The effective portion, which is between 7-19 seconds, has been obtained by using Housner and Arias intensity methods with DEEPSOIL software [48] as shown in Fig.…”

Historical structures should be carefully preserved and transferred to the next generations. Therefore, their seismic performances should be investigated in detail. In the finite element method, many parameters affect the seismic behaviour and damage distribution in the structures. One of the most significant parameters is the Soil-Structure Interaction effect. In finite element analyses, the soil medium is generally neglected, and the structures' base is restrained by fixed supports. In this study, seismic response of a historical masonry minaret is investigated by considering the Soil-Structure Interaction and Operational Modal Analysis methods. To determine the effect of Soil-Structure Interaction on structural behaviour, the fixed supports, hard and soft soil mediums at the base of the structure are modelled. The material and failure behaviours are defined with the Concrete Damage Plasticity model. Displacements, principal stresses, damage rates, and damage distribution of models are obtained with nonlinear time history analyses. According to the results, the interstory drift increases due to the decrease in the stiffness of the soil media. In addition, the fixed supports model was damaged more tensile stress damage than the other models. The least occurred in the soft soil model. It is concluded that the Soil-Structure Interaction effect significantly affects structural behaviour, especially the damage rate and distribution.

The interaction between soil and structure plays a crucial role on accurate determination of structures' seismic behavior. The assumption of fixed base structure has been commonly used in traditional design works, and the interaction between soil and structure is thus often neglected. In addition, historical masonry structures particularly built on elastic soil media may be significantly affected seismic behavior of the structure under earthquakes. In this research, the damage distribution on a historical masonry minaret is numerically investigated under horizontal earthquake ground motion. AlacaMosque minaret was built in 1271 in Bolvadin district of Afyon province. The historical masonry minaret was chosen as the subject of the study. Nonlinear seismic time history analyses were conducted for fixed-based and different soil properties under horizontal earthquake ground motion. The horizontal (East-West) component acceleration records of Dinar earthquake (Mw = 6.1) that took place on October 10, 1995, were used during the analyses. Maximum displacement, maximum/minimum principal stresses, and damage ratios were determined by nonlinear analyses performed considering fixed base and soil-structure interaction. The analysis results showed that soil-structure interaction had significant effect on the structural behavior of the minaret, such that, the minaret that was expected to get damage in the case of fixed base did not get any damage when soil-structure interaction was considered.
