Kazık Temel Sistemlerinin Seçimi: Bütünleşik Çok Kriterli Karar Verme

Öz

Yüklerin yapıdan zemine iletilmesi için kazıklı temeller kullanılmaktadır. Kazık temel tasarımı, kazık tipi, kazık çapı, kazık uzunluğu, kazık düzeni vb. gibi tasarım parametrelerinin belirlenmesini içerir. Bu çalışmada, belirli bir zemin profili için en uygun kazıklı temel tasarımını seçmek amacıyla bütünleşik bir metodoloji önerilmiştir. Bu metodoloji, Analytical Hierarchy Process (AHP), Vlsekriterijumska Optimizacija I Kompromisno Resenje (VIKOR), Preference Ranking Organization Method for Enrichment Evaluations (PROMETHEE) ve sonlu Elemanlar Analizi içerir. AHP, kriterlerin ağırlıklarını belirlemek için kullanılırken, VIKOR ve PROMETHEE alternatiflerin nihai sıralamayı elde etmek için kullanılır. Daha hassas sonuçlar elde etmek için seçilen en iyi alternatifler kümesine sonlu eleman analizi uygulanır. Önerilen metodolojinin etkinliğini göstermek için bir örnek çalışma yapılmıştır. Örnek çalışmasının sonuçları, önerilen metodolojinin kazıklı temel seçimi için uygun bir karar verme yaklaşımı olduğunu göstermiştir.

Selection of Pile Foundation Systems:An Integrated Multi-Criteria Decision Making

Öz

Pile foundations have been used for transmitting loads from structure to the soil. Design of pile foundation involves the determination of the design parameters such as pile type, pile diameter, pile length, pile layout etc. This study proposes an integrated methodology for selecting the most appropriate pile foundation design for a given soil profile. The methodology incorporates Analytical Hierarchy Process (AHP) and Vlsekriterijumska Optimizacija I Kompromisno Resenje (VIKOR)/Preference Ranking Organization Method for Enrichment Evaluations (PROMETHEE) and Finite Element Analysis (FEM). While AHP is used for determining the weights of criteria, VIKOR and PROMETHEE are employed in order to acquire final rankings of alternatives. Then, a finite element analysis is applied on a selected set of best alternatives to provide precise results. Finally, a case study is conducted to show the effectiveness of the proposed methodology. Based on the findings of the case study, the methodology proposed paves the way for making an efficient decision for pile foundation selection.
