    2007 ve 2018 Deprem Yönetmeliklerinin Yapısal Analizler IşığındaKarşılaştırılması
    (2021) Adar, Kübra; Büyüksaraç, Aydın; Işık, Ercan; Ulu, Ali Emre
    Depremlerden dolayı meydana gelen yapısal hasarları ve bu hasarlar sonucu oluşan can kayıplarını en aza indirmek amacıyla depremedayanıklı yapı tasarım kuralları hazırlanmaktadır. Bilimsel gelişmeler, yapım teknolojileri ve yapı malzemelerindeki yenilikler iledepremde oluşan hasarların birlikte dikkate alınması sonucu, yenilenme ve değişim ihtiyacı kaçınılmazdır. Bu çalışma kapsamında 2007ve 2018 deprem yönetmelikleri arasında karşılaştırmalar yapılmıştır. Kullanılan yazılımın uygun sürümleri kullanılarak, örnek olarakseçilen on beş katlı betonarme bir yapı her iki yönetmelik için analiz edilerek sonuçlar karşılaştırılmıştır. Analizler sonucu örnek olarakincelenen bina için değişimler belirtilerek, yorumlar yapılmıştır.

    A Study on Damages in Masonry Structures and Determination of Damage Levels in the 2020 Sivrice (Elazig) Earthquake
    (Springer Science and Business Media Deutschland GmbH, 2023) Işık, Ercan; Ulu, Ali Emre; Büyüksaraç, Aydın; Aydın, M. Cihan
    One of the main tectonic elements of Turkey is the Eastern Anatolian Fault zone. An earthquake with a magnitude of Mw = 6.8 on this fault on 20 January 2020 in Sivrice (Elazığ) district caused loss of life and property. Seismic parameters were obtained for the five closest earthquake station locations to the earthquake in the region, which is very active in terms of seismicity. The peak acceleration values predicted in the earthquake hazard map and codes were compared with the measured values. The measured acceleration values were considerably smaller than the acceleration values recommended for the building design. In this study, damage grading was also made depending on the damages in the masonry structures. Damage classification was actualized using the damage levels for masonry structures predicted in the European Macro-Seismic Scale (EMS). Information about the causes of damage in masonry structures and solution suggestions are given.

    Damage evaluation of masonry buildings during Kahramanmaras (Turkiye) earthquakes on February 06, 2023
    (Techno-Press, 2023) Isik, Ercan; Buyuksarac, Aydin; Avcil, Fatih; Arkan, Enes; Aydin, M. Cihan; Ulu, Ali Emre
    The Mw=7.7 (Pazarcik-Kahramanmaras) and Mw=7.6 (Elbistan-Kahramanmaras) earthquakes that occurred in Turkiye on 06.02.2023 with 9 hours' intervals, caused great losses of life and property as the biggest catastrophe in the instrumental period. The earthquakes affecting an area of 14% of the country were enormous and caused a great deal of loss of life and damage. Numerous buildings have collapsed or damaged at different levels, both in the city centers and in rural areas. Within the scope of this study, masonry structure damage built from different types of materials in the earthquake region was taken into consideration. In this study, the damage and causes of such masonry structures that do not generally receive engineering services were examined and explained in detail. Insufficient interlocking between wall-wall and wall-roof, inadequate masonry, lack of horizontal and vertical bond beams, usage of low-strength materials, poor workmanship, and heavy earthen roof are commonly caused to structural damages. Separation at the corner point and out-of-plane mechanism in structural walls, and heavy earthen roof damages are common types of damage in masonry structures.

    Snow Avalanche Risk Assessment using GIS-Based AHP for Bitlis Province
    (2023) Aydın, M.; Birincioğlu, Elif Sevgi; Ulu, Ali Emre; Büyüksaraç, Aydın
    Bitlis province, located in the Eastern Anatolia of Turkey, is the region with the highest snowfall in the country. Due to its highland and steep structure, the region is at high avalanche risk. The assessment of snow avalanche risks is critical in modern disaster management. In this study, the avalanche risks were assessed using the analytical hierarchy process (AHP), which is an effective multiple criteria decision-making method. The avalanche risk was considered to depend on many factors, such as temperature, slope, elevation, aspect, land use, soil, lithology, precipitation, distance to the fault and population. The outputs obtained from the method were mapped in the GIS environment, and thus the avalanche risks of the region were determined. According to the results, especially the highland and steep southern parts and the two volcanic mountain foothills in the region were evaluated as high risk. The study results were validated by comparing past avalanche events and some previous research.
