    Large-scale loss of life and property occurred in Kahramanmaras and its districts, which are the city center where the epicenters of the earthquake couples that occurred on February 6, 2023, in Turkiye. Major damage has occurred in different structural systems due to the earthquake. In addition, fault traces that are the source of the earthquake were clearly observed on the ground surface. In this study, the effects of both earthquakes on soil, reinforced concrete, masonry, prefabricated, and other structural systems were evaluated observationally in Kahramanmaras and its districts. Comparisons were made on the last two earthquake maps used in Turkiye for the locations of strong ground motion measuring devices in Kahramanmaras. The masonry structures, which are common in rural areas in the epicenter, have been heavily damaged because they have not received engineering service. However, it is seen that the concrete buildings have insufficient strength and ductility. A similar situation is also present in industrial precast structures, and it has been observed that the damaged and collapsed in these structures are manufactured without complying with the type connection details given for prefabricated reinforced concrete structures in the codes. It has also been observed that the soil-structure interaction is the most determining parameter in the structure's performance in these earthquake couples. Especially in weak soils, the damage to the structures has been quite heavy. The field data obtained from the earthquakes showed that some of the conditions of the current earthquake code should be discussed again.

    Seismic performance of masonry structures after 06 February 2023 earthquakes; site survey and FE modelling approach
    (Elsevier Sci Ltd, 2024) Izol, Rabia; Isik, Ercan; Avcil, Fatih; Arslan, Musa Hakan; Arkan, Enes; Buyuksarac, Aydin
    The Kahramanmaras, earthquake couple, which took place on February 6, 2023, is one of the biggest disasters T & uuml;rkiye has encountered in the instrumental period. While the effects of these earthquakes were felt primarily in 11 different provinces, they also caused significant effects in many other provinces. These two independent earthquakes of magnitude 7.7 and 7.6, which are rare in the history of literature, occurred 9 h apart and caused more structural damage. Serious losses of life and property occurred in Kahramanmaras,, the epicenter of both earthquakes. In this study, structural damages on masonry buildings in rural areas of Kahramanmaras, province are examined in detail within the framework of the cause-effect relationship. Different building samples are evaluated for each damage situation. In addition, nonlinear time history analyses were performed on a sample structure and the damage was examined in detail. In general, these structures, which do not receive engineering services, exhibit typical masonry structure damage as in other earthquakes. This study provides information about the behavior of such buildings under earthquake loads and emphasizes the importance of receiving the necessary engineering services for these structures.
