“…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.

“…Three different modeling methods are used in modeling masonry structures, namely detailed micro, simplified micro and macro modeling techniques (Fig. 4) [10,17,[26][27][28][29]. In micro modeling technique, mortar material and masonry elements (stone or brick material) are modeled separately (Fig.…”

“…Linear or nonlinear dynamic analysis are performed to establish more realistic seismic behavior of the bridges by creating numerical models [6][7][8][9][10]. In order to examine the earthquake performance of the bridges, dynamic behavior is determined by using different calibration methods in many studies and numerical models are calibrated according to this behavior [11][12][13][14].…”

The goal of this study is to investigate the behavior and failure mechanism of historical Irgandi Bridge located in Bursa City under earthquake loads by using linear and nonlinear dynamic analysis. Dynamic characteristics of the bridge is investigated by using in-situ Operational Modal Analysis (OMA) tests. The finite element model is updated according to the OMA tests. Three different artificial earthquake records from weak to very strong are applied to the model for understanding the damage zones and the failure mechanism of the historical bridge. The results show that the bridge does not reach the failure mechanism under weak earthquakes for nonlinear dynamic analysis. However, under strong earthquake even if damage zones are occurred and the stiffness of the bridge is decreased, there is no failure mechanism observed according to the nonlinear dynamic analyses. Under very strong earthquake loads the bridge reaches the failure mechanism according to the nonlinear dynamic analysis. As the earthquake level increases, the difference between linear and nonlinear dynamic analysis results increases due to structural damages. In addition, considering the soil-structure interactions, it is concluded that the dynamic characteristics could be reflected more accurately.

Historical structures which are cultural heritage have been frequently damaged or ruined because of unexpected events such as earthquakes. Masonry arch bridges constitute a significant part of historical structures. In this study, the single-span Murat Bey Bridge in the province of Kütahya, built in 1460, was selected as a numerical application. Three dimensional finite element model of the bridge was generated with SAP2000 finite element program. The dynamic characteristics of the bridge were obtained by modal analysis method. Firstly, static analysis of the bridge under its own weight was carried out. Then, time-history analysis method was used for seismic evaluation of the bridge. For this purpose, the acceleration records of the 1998 Adana, 2003 Bingöl, 2011 Van and 2020 Elazığ earthquakes were taken into consideration. As a result of the dynamic analyses carried out, the displacement and stress graphs occurring on the bridge were examined. The highest displacement and stress values on the historical bridge were obtained from the acceleration records of the 2011 Van earthquake.
