    Döşemelerdeki Boşluk Konumunun Kayma Gerilmesine Etkisinin İncelenmesi
    (2010) Öncü, Mehmet Emin; Ulucan, Zülfü Çınar; Yön, Burak
    Bu çalışmada, betonarme binaların döşemelerinde oluşturulan boşlukların plandaki yerleşiminin yapıların davranışına etkisi incelenmiştir. Döşemelerdeki düzensizliğin incelenmesi için yapı planının değişik yerlerinde boşluk bulunan üç adet çok katlı düzensiz bina ve bir adet düzenli bina modeli tasarlanmıştır. Zaman Tanım Alanında Hesap yöntemi kullanılarak, bu bina modellerinin doğrusal dinamik analizleri yapılmıştır. Bu analizler için 13 Mart 1992 yılında meydana gelen Erzincan Depreminin ivme kayıtları kullanılmıştır. Seçilen binaların döşemelerinin esnek diyafram şeklinde davrandığı kabul edilmiştir. Çözümlerde SAP2000 Yapısal Analiz Programı kullanılmıştır. Seçilen binaların dinamik analizinden elde edilen boşluğa komşu döşemelerdeki kayma gerilmeleri karşılaştırmalı olarak değerlendirilmiştir. Buna göre bina döşemelerindeki boşluk yerinin yapıların davranışını değiştirdiği ve döşemelerde büyük kayma gerilmeleri oluşturduğu belirlenmiştir.

    Field reconnaissance and structural assessment of the October 30, 2020, Samos, Aegean Sea earthquake: an example of severe damage due to the basin effect
    (Springer, 2022) Onat, Onur; Yön, Burak; Öncü, Mehmet Emin; Varolgüneş, Sadık; Karaşin, Abdulhalim; Cemalgil, Selim
    An earthquake with a magnitude ranging from Mw = 6.9 (KOERI) to Mw = 7.0 (USGS) struck Samos Island in the Aegean Sea on October 30, 2020, with an epicentre 70 kms from the Izmir city centre in Turkey. The earthquake took place at 14:51 local time (11:51 UTC). The peak ground acceleration (PGA) of this earthquake was recorded to be 0.179 g at the epicentre of the earthquake. This earthquake occurred at a depth of 17.26 km (AFAD (2020) Izmir Earthquake Report, (In Turkish)) and lasted 16 s. The main shock from the earthquake triggered a tsunami that hit the building stocks built near the coast. During the gradual deregulation of COVID-19 pandemic regulations, various events caused considerable damage to the building stock, particularly in the Izmir Seferihisar and Bayrakli regions and resulted in a massive disruption of daily habits. The main shock caused 117 deaths in both Turkey and Greece, and 1632 people were also injured in Turkey. Moreover, several injuries occurred in Greece. A total of 103 buildings collapsed, 700 were severely damaged, 814 buildings were moderately damaged, and 7889 were slightly damaged. The basic aim of this paper is to briefly present the past and present seismotectonic characteristics of the region, present building stock, and former structural conditions before the earthquake, assess structural performance and classify distinguished earthquake-induced failures and damage due to the basin effect.

    Seismicity of East Anatolian of Turkey and failures of infill walls induced by major earthquakes
    (World Scientific Publication, 2021) Doğangün, Adem; Yön, Burak; Onat, Onur; Öncü, Mehmet Emin; Sağıroğlu, Serkan
    There are three major fault zones in Turkey scattered around the country known as East Anatolian Fault (EAF), North Anatolian Fault (NAF) and Anatolian-Aegean Subduction Zone (AASZ). Last two decades, EAF has been rather quiescent compared with NAF. However, this quiescence was broken in the beginning of the millennium. The strong shaking was started in 2003 with Bingol earthquake (Mw = 6.3) and the last earthquake on the EAF is the Sivrice-Elazig (Mw = 6.8) on January 24, 2020. Strong seismicity of these faults damaged the structures severely and caused death of the habitants. This study aims to present, seismotectonic of the region, general characteristics of the earthquakes and more specifically to report structural damage of infill walls of the structure's damages caused by these earthquakes. Damage evaluation and identification of the observed infill wall damages due to 2003 Bingol, 2011 Van earthquakes and January 24, 2020 Sivrice-Elazig earthquake occurred Turkey's Eastern region, were presented, and possible solutions were suggested. Moreover, the effects of the infill walls on the behavior of structures under static and dynamic load cases are discussed that experienced in these earthquakes. Damages are classified according to formations such as in-plane or out-of-plane, evaluations and the results obtained from the discussions are presented for each category
