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

Öz

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.
