Abstract

In this study, a Particle Swarm Optimization (PSO) based algorithm is used for optimum design of reinforced concrete cantilever retaining walls. Besides vertical loads, both active and static lateral ground pressures are considered for design. Reinforced concrete design rules defined in TS-500 and checking procedures about sliding, overturning and bearing capacity failures defined in TS-7994 are taken into account as constraints of the optimization problem. In order to evaluate the relationship between optimum design results and values of PSO solution parameters, a sensitivity analysis is performed. Results show that, PSO based solution algorithm may be used as an efficient tool for optimum design of reinforced concrete cantilever retaining walls by satisfying all considered constraints.

Betonarme konsol istinat duvarlarının parçacık sürü optimizasyonu ile optimum tasarımı

Abstract

Bu çalışmada, betonarme konsol istinat duvarlarının optimum tasarımı için Parçacık Sürü Optimizasyonu (PSO) tabanlı bir algoritma kullanılmıştır. Tasarımda düşey yüklerle beraber statik yatay zemin itkileri de dikkate alınmıştır. TS-500’de yer alan betonarme tasarımı ile ilgili koşullar ve TS-7994’te yer alan kayma, devrilme ve taşıma gücü kontrolleri ile ilgili koşullar, optimizasyon probleminin kısıtları olarak ele alınmıştır. Tasarım sonuçlarının PSO çözüm parametrelerine duyarlılığını araştırmak amacıyla bir duyarlılık analizi yapılmıştır. Elde edilen sonuçlar PSO tabanlı çözüm algoritmasının, betonarme konsol istinat duvarlarının dikkate alınan kısıtlar sağlanacak şekilde optimum tasarımında etkili bir araç olarak kullanılabileceğini göstermiştir.
