“…Macro modeling, on the other hand, is an equivalent material model that accepts the building element as composite and reflects the common feature of these materials, without making any distinction between stone and brick blocks and mortar [34]. This method is generally preferred because it significantly reduces the computer solution time in modeling large systems [26]. The three-dimensional solid model of the Historical Masonry Karaz bridge to be used in this study, prepared in the ABAQUS program, is given in Figure 9 and its geometric properties are given in Figure 10.…”

The most significant artifacts that transfer the cultural heritage of past civilizations to the present are historical structures. Historical bridges are of great importance in terms of transportation, trade and architecture from past to present. Some of these structures have been destroyed by natural disasters or have suffered significant structural damage. Especially earthquakes cause damage to these structures. In this study, the earthquake behavior of the Historical Karaz Bridge was investigated. The structural elements of the bridge and the materials connecting the bearing elements were evaluated together with the macro modeling approach. For this purpose, a 3D finite element model of the bridge was generated and its seismic behavior under different ground motion records was investigated by nonlinear analysis. Analyzes were carried out using the ground motion records of Bingöl, Elazığ, Erzincan, Van and Gölcük, and the results were evaluated mutually. In the analysis results, the dynamic behavior of the bridge was evaluated over the distribution of displacements and stresses and the earthquake behavior was investigated.

“…The macro modeling technique is one of the commonly used masonry structural modeling techniques in the literature. The historical masonry bell towers in South-East Lombardy in Italy [63], historical fortified masonry palaces in Switzerland and Northern Italy [64], Emir Bayındır Bridge in Turkey [65], San Pietro and San Benedetto churches in Italy [66], Torre De la Vela in Spain [67], Gaskar brick minaret in Iran [68] and five historical masonry minarets in Antalya (Turkey) [69] are some of the studies examining the seismic behavior of different types of structures using this type of structural modeling technique. While doing this type of modeling, analyses are carried out without making any distinction between the binding material (mortar, etc.)…”

Masonry structures began to be built with the existence of human beings and are an inspiration for today’s structures. Monumental historical buildings built according to people’s religious beliefs have special importance among such structures. Despite being exposed to many natural disasters over time, such structures that have survived till today are an indispensable part of the historical heritage. Within the scope of this study, structural analyses were carried out for the historical Ulu Mosque’s minaret in Bitlis (Turkey), located in the Van Lake basin, using both on-site measurements and finite element methods. Detailed historical and architectural features were given for the minaret and the mosque. In addition to four different earthquake ground motion levels of 2%, 10%, 50% and 68%, structural analyses were deployed separately for seven different geographical locations in the same seismic risk area. Moreover, time history analyses were conducted using the acceleration records of the Van earthquake that occurred in the region. The minaret performance levels were determined by using the displacement values obtained. The study examined the different probabilities of exceedance and the changes in the regions with the same seismic risk. As a result of each structural analysis, base shear forces, displacement, period and maximum stress values were obtained for the minaret. The displacement, base shear force, and stress values increased as the exceedance probability decreased. While the same seismic and structural analysis results were obtained for the selected settlements in the same earthquake zone in this study, remarkable differences were observed for these settlements using the geographical-location-specific design spectrum.

“…In this context, a structural analysis of such structures is an important engineering activity. There have been many studies on the structural analysis of historical structures in different parts of the world [7][8][9][10][11][12][13][14][15][16][17][18]. Many of these studies presented the reasons and results of the damages that occurred within selected historical buildings and proposed solutions for these problems.…”

Tombs are an important part of the architecture in the ancient civilizations. Ahlat is a district located in the Lake Van Basin and has hosted many civilizations with its rich historical texture, a large part of which consists of tombs. In this study, observational structural analyses were performed for fifteen different tombs in the Ahlat district. Because of the investigations carried out in the field, the geometrical locations of the ditches were determined and mapping was carried out for these tombs. Damages in the tombs caused by natural reasons were determined and information about the preservation measures to be taken was provided. Finite element models were created for two selected tombs with different architectural characteristics that may represent the other tombs. The study aimed at determining the seismic behavior of the tombs for which two selected tombs were analyzed. Monumental buildings for historical heritage should be preserved for the next generations, which is possible if they could be investigated for structural characterizations. This study sets an example in that direction. The traceability of such structures is crucial for interventions in the historical buildings, which will become more practical with the help of the observational forms.
