“…Seismic performance assessment and failure mechanisms for historic structures were well studied in various research [5,[12][13][14][15][16][17][18][19][20][21][22][23][24]. Simpli ed methods were also developed for seismic vulnerability evaluation and the kinematic limit analysis [25,26].…”

This study aims to present eld research and evaluate the common failure types for most of the cultural heritage buildings in an ancient district of Antakya (Antioch) after the two consecutive devastating earthquakes occurred in Kahramanmaraş, Turkey on February 6, 2023. The rst one occurred at 04:17 (01:17 UTC), a moment magnitude (Mw) 7.7 (AFAD, Disaster, and Emergency Management Presidency), an earthquake occurred in Pazarcık-Kahramanmaraş and it was followed by another earthquake at 13:24 (10:24 UTC), an Mw 7.6 earthquake at Elbistan-Kahramanmaraş. For the post-reconnaissance evaluation of the cultural heritage buildings in Antioch, a eld trip was arranged to the site. Since the aftershocks were happening, the eld trip was extremely dangerous, especially around damaged or heavily damaged structures. The use of laser scanners made it possible for safer documentation of these structures. The cultural heritage structures studied herein are in an ancient part of Antakya (ancient Antioch) called Kurtuluş Caddesi (Rue Jadid, yeni cadde). Damages on the registered heritage buildings in this study are classi ed as in different damage levels. One of the most common failure types observed is the out-of-plane movement of the walls. Exhaustion of the in-plane strength capacity of the walls is followed by an out-of-plane mechanism. Many other failure types are either due to the absence of engineering practices or false restoration practices. As a case study, some of these structures are examined by simpli ed limit analysis and the results are presented. Even though restoring these structures depends on many variables and various stakeholders, a simple guide for restoration is provided for the elimination of similar problems for future events.

“…Weaknesses of the structures are determined through numerical simulations, allowing more appropriate strengthening work to be carried out. In the literature many studies were made about numerical simulations of historical masonry structures such as masonry bridges [1][2][3], buildings [4][5][6][7], churches [8][9][10][11], mosques [12,14], minarets and towers [15][16][17][18] etc. Such numerical studies are very effective tools in obtaining the structural behavior of historical structures.…”

Although historical masonry structures are highly aesthetic, they harbor numerous structural uncertainties. These structures encompass information such as the date of construction, construction methods, material properties, design details and more. They possess diverse identities in various aspects, making the structural assessment of historical buildings a challenging task. Consequently, all historical buildings should be treated with special consideration, and suitable solutions must be devised. In this study, the structural damage causes of the entrance gate of the Harran Grand Mosque (Ulu Cami), which had undergone recent restoration but suffered damage once again during the Kahramanmaraş earthquakes on 6 February 2023 have been investigated. A three-dimensional finite element model of the structure was developed using Abaqus software. In the numerical studies the static as well as non-linear dynamic earthquake analyses were conducted to evaluate the reasons of the collapse of the structure. The structure was subjected to earthquakes from different directions and its compatibility with actual damage scenarios was observed. The study results are presented with contour diagrams of displacement, stress and damage situations. Upon reviewing the numerical findings obtained from the study, it is evident that the actual damage condition of the structure can be reasonably simulated. As a result, it is thought that the earthquake hit the entrance arches from out of plane which caused the collapse. To sum up, by evaluating the damage conditions resulting from such numerical studies, restoration applications can be handled more effectively, ensuring that correct interventions are carried out.

“…These analyses assist engineering and architectural teams in understanding the mechanical behavior of these structures and contribute to determining appropriate strengthening and restoration strategies. Many studies have been conducted to numerically determine the structural behavior of historical structures, such as buildings [3][4][5][6], mosques [7][8][9], churches [10][11][12][13], masonry bridges [14][15], minarets, and towers [16][17][18][19] etc. Numerical studies have shown that the evaluation of the structural behavior of historical masonry structures is prevalent and effective.…”

Historical masonry structures with aesthetic aspects play an important role in cultural heritage. However, such structures are vulnerable to seismic effects. Therefore, periodic maintenance and structural evaluations are required for these structures. In this study, a historical masonry building called the Pertev Pasha Mansion, located in Trabzon, Turkey, was selected for the evaluation. The building was demolished in the last few years and has been planned to be rebuilt in its original form. In the study, the finite element model of the building was created based on reconstruction drawings. Modal analysis was performed to obtain the frequencies and mode shapes of the building. Finally, seismic analyses were conducted based on the February 6 Kahramanmaraş earthquakes for two different acceleration records that were collected from different stations, one near the epicenter (Pazarcık station) of the earthquake and the other near the building (Ortahisar station). From the results of the modal analysis, the frequency and mode shapes of the structure were obtained. The displacement and stress results were obtained from the seismic analysis and presented with contour diagrams. At the end of the study, a general evaluation considering the novel Turkish guidelines for historic structures was conducted. According to the results of the seismic analysis performed using the Pazarcık station data, the drift ratio values of the structure exceeded 0.7%, which corresponds to the Collapse Prevention (CP) performance level. However, according to the seismic analysis results obtained using Ortahisar station data, the maximum drift ratio of the structure was 0.001%, corresponding to the Limited Damage (LD) performance level. Consequently, if the building had been built close to the center of the earthquake, it was likely to collapse, but it was estimated that it would have received limited damage because its current location was far from the center of the earthquake.
