Bir doğrultuda birleşik eğilme etkisindeki tekil temellerin çeşitli sezgisel algoritmalarla TS500’e göre minimum maliyetle optimum tasarımı

Bu çalışmada betonarme tekil temellerin minimum maliyetle optimum tasarımları Yapay Arı Koloni, Guguk Kuşu Arama, Öğretme-Öğrenme Tabanlı Optimizasyon Algoritması adlarıyla bilinen çeşitli sezgisel algoritmalarla gerçekleştirilmiştir. Söz konusu algoritmalarla gerçekleştirilen optimum tasarımlardan elde edilen bulgular çeşitli başarım (performans) ölçütlerine göre değerlendirilmiştir. Algoritmalardan en yüksek başarımı ve en yüksek yakınsama hızını öğretme ve öğrenme tabanlı optimizasyon algoritması göstermiştir. Diğer taraftan temelin eğilme momenti ve normal kuvvet düzeyi ile temel zeminin taşıma gücünün optimum tasarıma etkisi birtakım parametrik çalışmalarla incelenmiştir. Gerçekleştirilen parametrik çalışmalardan normal kuvvetin artmasıyla tekil temelin minimum maliyetinin arttığı, ayrıca dış merkezlik düzeyinin artmasıyla bu artış düzeyinin de yükseldiği anlaşılmıştır. Zemin emniyet gerilmesinin artmasıyla temelin minimum maliyetinin azaldığı görülmüştür.

Cost optimum design of spread footing under uniaxial combined bending according to TS500 via various metaheuristic algorithms

In this study, optimum designs of reinforced concrete spread footings bases with minimum cost were realized with various metaheuristic algorithms known as Artificial Bee Colony, Cuckoo Search, Teaching-Learning-Based Optimization Algorithm. The findings obtained from the optimum designs performed by the algorithms are evaluated according to various performance criteria. Teaching-Learning-Based optimization algorithm showed the highest performance and convergence speed. On the other hand, the effect of bending moment-axial force level, bearing capacity of soil on the optimum design of the spread footing are investigated by some parametric studies. It is understood that the increase in axial force increases the minimum cost of the spread footing and the increase in the eccentricity level rises the degree of increase. It has been observed that the minimum cost of spread footing has decreased with the increase of the bearing capacity of soil.
