Abstract

Bu çalışmada, rüzgârların oluşturabileceği dalgalara maruz kalabilen ceket tipi açık deniz yapıları incelenmiştir. Bu amaçla; yapısal davranışının belirlenebilmesi için farklı yükseklikleri olan 3 adet sayısal model, platformu ile birlikte tasarlanmıştır. Çalışma kapsamında, dalga periyotları ve dalga yükseklikleri parametre olarak kabul edilmiştir. Oluşturulan modellere dalga ve rüzgâr kuvvetleri birlikte etki ettirilerek çok adımlı doğrusal statik analizleri gerçekleştirilmiştir. Ayrıca modellerin lineer sınır değerlerinin belirlenebilmesi amacıyla statik itme analizleri gerçekleştirilmiştir. Analiz sonuçlarında, incelenen ceket tipi açık deniz yapılarının davranışını belirlemede dalga periyoduna göre dalga yüksekliğinin daha etkin olduğu saptanmıştır. Her üç modelinde dalga ve rüzgâr kuvvetleri altında elde edilen analiz sonuçlarından, dalga yüksekliği arttıkça yatay deplasmanlarının arttığı ancak modellerin yine de lineer sınırlar içinde kaldığı tespit edilmiştir.

Investigation of Behavior of Offshore Structures under the Effect of Changing Wave Periods

Abstract

In this study, coat-type open sea structures that can be exposed to waves that the winds can form have been investigated. For this purpose; 3 numerical models with different heights were designed together with the platform in order to determine the structural behavior. In the scope of the study, wave periods and wave heights are accepted as parameters. Multi-step linear static analyzes were performed by applying wave and wind force to the models created. Also, in order to determine the linear limit values of the models, static push analyzes were performed. In the results of the analysis, it was determined that the wave height was more effective than the wave period in determining the behavior of the investigated jacket type offshore structures. From the analysis results obtained under the wave and wind forces in all three models, it was found that the horizontal displacements increased as the wave height increased, but the models remained within the linear limits.
