Açık deniz yapıları kova temel sistemi davranışının
tahmini ile ilgili henüz yeterli bilgi birikimine ulaşılmamıştır. Açık deniz
koşullarında temel sistemlerinin ağır tekrarlı yüklere maruz kalması nedeniyle
zeminde kalıcı deplasman ve aşırı boşluk suyu basıncı gelişimi meydana gelir. Çalışmada
çok ayaklı temel sitemi ile tasarlanmış açık deniz yapısının bir kova temelinin
eksenel tekrarlı yükler altındaki davranışı sayısal analiz yöntemi ile
incelenmiştir. Özellikle yük frekansının davranış üzerindeki etkisine
odaklanılmıştır. Suya doygun zemin hipoplastik malzeme modeli ve iki fazlı üç
boyutlu sonlu elemanlar ile modellenmiştir. Analiz sonuçları, tekrarlı yük
frekansının zeminde aşırı boşluk suyu basıncı gelişimi ve temelin deplasman
birikimi üzerinde oldukça önemli etkileri olduğunu göstermiştir.
