Abstract

In this study, the optimum design of the reinforced concrete (RC)
footings subject to the axial load and bi-directional flexure was
performed by using Differential Evolution (DE) algorithm. The
minimum cost of concrete and steel materials was targeted in the
developed approach as the decision variables of foundation dimensions,
reinforcement numbers and diameters. In addition to seven different
decision variables, eighteen different constraint functions are included
in the optimization model for the TS-500 Standard requirements.
Optimum solutions of many different reinforced concrete footing
examples are presented by creating different axial load ratios,
eccentricity and allowable bearing value of soil scenarios. It has been
shown that a DE-based solution approach can be used effectively in the
optimum design of a reinforced concrete footing.

İki doğrultuda birleşik eğilme etkisindeki betonarme tekil temelin diferansiyel evrim algoritması kullanılarak optimum tasarımı

Abstract

Bu çalışmada iki doğrultuda bileşik eğilme etkisindeki betonarme tekil
temellerin Diferansiyel Evrim (DE) algoritması kullanılarak optimum
tasarımı gerçekleştirilmiştir. Temel boyutları, donatı sayısı ve çapı
kesikli karar değişkeni olarak geliştirilen yaklaşımda, beton ve çelik
malzemelerinin minimum maliyeti hedeflenmiştir. Yedi farklı karar
değişkenine ilave olarak TS-500 Standart gereklilikleri için on sekiz
farklı kısıt fonksiyonu optimizasyon modeline dahil edilmiştir. Farklı
eksenel yük oranları, eksantiriste ve zemin emniyet gerilme senaryoları
oluşturularak birçok farklı tekil temel örneğinin optimum çözümleri
sunulmuştur. DE tabanlı bir çözüm yaklaşımının, betonarme tekil
temelin optimum tasarımında etkin bir şekilde kullanılabileceği
görülmüştür.
