“…Also observations from the earthquake damages are discussed and compared with Turkish Earthquake Code and Turkish Building Code requirements. Bayraktar et al (2007a) investigated the performance of masonry stone buildings during the 25 and 28 March 2004 Akale (Erzurum) earthquakes in Turkey. Bayraktar et al (2007b) investigated the behaviour of masonry buildings during the 2 July 2004 Dogubayazit (Agri) earthquake in Turkey.…”

Abstract. This paper evaluates the performance of masonry buildings during the 20 and 27 December 2007 Bala (Ankara) earthquakes. Bala is a township located 50 km southeast from Ankara city in Turkey. The majority of the buildings in the affected region are built in masonry. Most of masonry buildings were formed with random or coursed stone and mud brick walls without any reinforcement. Many of these buildings were damaged or had collapsed. The cracking and failure patterns of the buildings are examined and interpreted according to current provisions for earthquake resistance of masonry structures. The damages are due to several reasons such as poor construction quality and poor workmanship of the buildings. In addition to these reasons, the two earthquakes hit the buildings within seven days, causing progressive damage.

“…However, these roofs lose their effectiveness because of weather conditions, such as rain and snow. Therefore, the residents place a new earthen cover on top of the existing roof to repair these roofs [16]. Thus, the weight and thickness of the roof increase over time.…”

Earthquakes are the most destructive natural hazards throughout human history. Hundreds of thousand people lost their lives and loss of billions of dollars' properties occurred in these disasters. Occurred medium or high-intensity magnitude earthquakes in last twenty years showed that these loses continue. For reinforced concrete (R/C) buildings, inappropriate design such as soft and weak stories, strong beam-weak column, short column, hammering, unconfined gable wall and in-plane/out-of-plane movement of the walls causes damages. These are the main reasons. In addition to this, low quality of structural materials, poor workmanship, lack of engineering services, and construction with insufficient detailing of the structural elements are the another reasons of damages. Main reasons of masonry building damages in terms of design faults can be shown as heavy earthen roofs, inappropriate detailing of wall to wall connection and wall to roof connection, absence of bond beams, large openings. However, construction of buildings by using local materials with poor workmanship on the base of traditional rules is the other reason of failures for these buildings. In this book chapter, earthquakes and reasons of damages arose from earthquakes for reinforced concrete and masonry structures were presented. In addition to this, appropriate solutions are suggested.

“…By leveraging finite element models of the structures under scrutiny, they substantiated the alignment between observed post-earthquake damages and those obtained from finite element analyses. Likewise, Decanini et al [13], Ahmedizadeh and Shakib [14], Bayraktar et al [15], Sayın et al [16], Atmaca et al [17], and Mercimek [18] meticulously examined the damage states of masonry structures in the aftermath of various seismic events, providing comprehensive reports on their findings. Yön and Onat [19], Kocaman and Kazaz [20], and Çelebi et al [21] conducted studies that examined the damage conditions of rural masonry structures in the vicinity of NAFZ and EAFZ, which are also the focus of this study, following moderate-sized earthquakes in 2015, 2020 and 2021.…”

On November 21, 2021, a 5.1 magnitude earthquake occurred with its epicenter in Erzurum-Köprüköy. In the eastern part of our country, most of the building stock in rural areas and certain parts of city center is made up of masonry structures. Most of the masonry structures consist of rubble stone walls with very low tensile strength. These load bearing elements, which are exposed to out-of-plane and in-plane displacements due to earthquakes, can be easily damaged due to their low tensile strength and poor manufacturing. In this study, the damage mechanisms of the masonry structures in the villages of Alaca, Kayabaşı, Marifet, and Sarıtaş have been reported. As a result of field studies, damages are quite prevalent due to inadequate connections between load-bearing walls and roof. Additionally, the weak connection between the leaves of load-bearing walls and lack of connection in the junctions of the walls have contributed to the damages. he observed damages can be generally classified as the quality of workmanship/construction, inadequate material characteristics, weak load bearing walls, lack of proper connections, failure of unconfined or high gable walls, heavy earth roof. Many of the damaged structures have not adhered to regulatory recommendations and are buildings that did not receive engineering services.
