Özet

Petrol depolama tankları, dinamik ve sismik yüklere dayanacak şekilde tasarlanmalıdır. Büyük hacme sahip petrol tanklarının depremler altında güvenliğinin sağlanması oldukça önemlidir. Deprem süresince arazi yüzeyi bütün yönlere doğru hareket etmekte ve bunun sonucu olarak tank titreşimlere maruz kalmaktadır. Özellikle arazi yüzeyine paralel hareketler tankta titreşimler meydana getirmekte, tank duvarlarında beklenmedik deformasyonlara neden olmaktadır. Bu çalışmada, sismik koşullar altında üç farklı geometriye sahip petrol tanklarında meydana gelebilecek muhtemel deformasyonlar doluluk oranlarına bağlı olarak incelenmiştir. Çalışmada sonlu elemanlar yöntemi temeline dayanan bir paket programdan yararlanılmıştır. Test edilen modellerin hızlanma ve deformasyon gibi numune tepkileri gözlemlenerek sonuçlar önceki çalışmalarla mukayese edilmiş ve doğrulanmıştır. Sonuçlar, yağ seviyesi, tank şekli ve mod değişimi arasında net bir ilişki olduğunu ortaya koymuştur. Daha yüksek yağ seviyesi, her durumda daha yüksek doğal frekans sundu. Tepki spektrum modeli, yağ seviyesi arttığında bir artış olduğu gözlemlendi.

Abstract

Oil storage tanks must be designed to withstand dynamic and seismic loads. It is very important to ensure the safety of oil tanks with large volumes under earthquakes. During the earthquake, the land surface moves in all directions and as a result, the tank is exposed to vibrations. Especially the movements parallel to the land surface create vibrations in the tank and cause unexpected deformations on the tank walls. In this study, possible deformations that may occur in oil tanks with three different geometries under seismic conditions are investigated depending on their filling ratios. In the study, a package program based on the finite element method was used. By observing the sample responses such as acceleration and deformation of the tested models, the results were compared and confirmed with previous studies. The results revealed a clear relationship between oil level, tank shape and mode change. The higher oil level offered higher natural frequency in any case. The response spectrum model observed an increase when the oil level increased.
