Abstract

Water tanks are critical structures that must be used without damage after an earthquake. Due to their vital importance, these structures are required to perform well under the influence of major earthquakes. In this study, the behavior of the RC elevated water tanks under earthquake effects was investigated. The water tank with a volume of 75 m3, which is widely applied as a type project, was examined according to the calculation principles of the 1968, 1975, 1998, 2007, and 2018 earthquake codes. The analysis of the structure designed in the SAP2000 program was carried out according to the equivalent linear method. When the analysis results were compared according to the earthquake codes considered, it was concluded that the structure showed better performance as the design criteria and calculation principles were improved from the 1968 earthquake code to the 2018 earthquake code. The comparative analysis results obtained from the study were evaluated specifically for an RC elevated water tank that was heavily damaged in the 6 February 2023 Kahramanmaraş earthquakes.

Betonarme Ayaklı Su Depolarının Türk Deprem Yönetmeliklerine Göre Davranışının İncelenmesi

Abstract

Su depoları depremden sonra hasarsız olarak kullanılması gereken kritik önemde yapılardır. Büyük depremler etkisi altında bu yapıların hayati öneminden dolayı iyi bir performans göstermesi istenir. Bu çalışmada betonarme ayaklı su depolarının deprem etkisi altında davranışı araştırılmıştır. Çalışmada tip proje olarak ülkemizde yaygın bir biçimde uygulanan 75 m3 hacimli su deposu, 1968, 1975, 1998, 2007 ve 2018 deprem yönetmelikleri hesap esaslarına göre incelenmiştir. SAP2000 programında tasarlanan yapının analizi eşdeğer deprem yükü yöntemine göre gerçekleştirilmiştir. Ele alınan deprem kodlarına göre analiz sonuçları karşılaştırıldığında, 1968 deprem kodundan 2018 deprem koduna kadar tasarım kriterleri ve hesap esasları geliştirildikçe yapının daha iyi bir performans gösterdiği sonucuna varılmıştır. Çalışmadan elde edilen karşılaştırmalı analiz sonuçları, 6 Şubat Kahramanmaraş depremlerinde ağır hasar alan ayaklı bir su deposu özelinde değerlendirilmiştir.
