Abstract

February 6 earthquakes, which occurred in Turkey and were called the disaster of the century, caused more than 50 thousand deaths and the collapse of around 40 thousand structures in 11 provinces. The main purpose of this study is to examine the effects of consecutive and aftershock earthquakes on concrete strength, considering the main earthquake. It is also aimed to reveal whether the comparison of the strength values obtained by testing the cores taken from buildings that have been destroyed in earthquakes in our country and the concrete class envisaged in the project concrete is correct or not. It was revealed because of experimental studies that fresh concrete is affected by earthquakes for up to 3 days and its strength decreases by 15-20%. In the coming years, it is possible that studies will be conducted using data obtained from earthquakes using artificial intelligence to reveal the decrease in strength, even for certain earthquake effects. Therefore, it is not a correct approach to directly compare the strength of the concrete class foreseen in the project of a building that has been subjected to an earthquake and turned into rubble with the strength of the cores taken from the rubble.

Özet

Türkiye’de meydana gelen ve asrın felaketi olarak adlandırılan 6 Şubat Depremleri 11 ilde 50 binden fazla can kaybına ve 40 bin civarında yapının yıkılmasına neden olmuştur. Bu çalışmanın temel amacı, ana depremin yanında ardışık ve artçı depremleri de dikkate alarak, depremin beton dayanımı üzerindeki etkilerini irdelemektir. Diğer taraftan ülkemizde özellikle depremde enkaz haline gelmiş binalardan alınan karotların deneye tabi tutulması sonucu elde edilen dayanım değerleri ile proje betonunda öngörülen beton sınıfının karşılaştırılmasının doğru olup olmadığının ortaya konulması da amaçlanmaktadır. Depremlerin beton dayanımı üzerindeki etkisi; taze ve sertleşmiş beton olarak iki ayrı grup beton üzerinde değerlendirilmiştir. Yapılan çalışmalar sonucunda, taze betonun 3 güne kadar depremden etkilendiği ve dayanımında %15-20 gibi belirli oranlarda düşüşler olduğu ortaya konulmuştur. Depreme maruz kalmış bir yapıdaki beton dayanımının depremden etkilenmesini her durumda geçerli olabilecek şekilde ortaya koyabilen bir çalışmaya yazarlar tarafından rastlanılmamıştır. Önümüzdeki yıllarda depremlerden elde edilen veriler kullanılarak yapay zekâ ortamında belirli deprem etkileri için de olsa dayanım düşüşünü ortaya koyan çalışmaların yapılması olasıdır. Dolayısıyla günümüzde deprem geçirmiş ve enkaz haline gelmiş bir bina için projesindeki beton sınıfı için öngörülen dayanımla, enkazdan alınan karotların dayanımlarını doğrudan karşılaştırmak doğru bir yaklaşım değildir. Zira henüz karot sonuçlarının nasıl değerlendirileceği yönetmelik ve standartlarımızda belli değildir.
