Abstract

As in other reinforced concrete structures, the traditional design process of retaining walls is based on the trial and error method. Regulation criteria are tried to be provided in the traditional design, but no special effort can be made except engineering hunch for minimum weight or cost of the structure. In this study, the optimum design of a retaining wall was performed by jaya algorithm as single objective function for minimum weight or cost and as a multi-objective function taking both together. As a result of the optimum design, the wall dimensions and the reinforcement to be used in the critical sections can be determined in details. The study also examines the performance of the algorithm on this cited problem.

Betonarme Konsol İstinat Duvarlarının Minimum Maliyet ve Ağırlıkla Optimum Tasarımı

Abstract

Diğer betonarme yapılarda olduğu gibi
istinat duvarlarının da geleneksel tasarım süreci deneme yanılma yöntemini
temel almaktadır. Geleneksel tasarımda yönetmelik kriterleri sağlanmaya
çalışılmakta, ancak yapının minimum ağırlıkta ya da minimum maliyetle tasarımı
için mühendislik önsezisi dışında özel bir çaba gösterilememektedir. Bu çalışmada
bir istinat duvarının optimum tasarımı minimum ağırlık veya minimum maliyet
için tek amaç fonksiyonlu ve her ikisi birlikte dikkate alınarak çok amaç
fonksiyonu olarak Jaya algoritmasıyla gerçekleştirilmiştir. Optimum tasarım
sonucunda duvar boyutları ve kesitlerde kullanılacak asal donatılar detaylı
olarak belirlenebilmektedir. Çalışmada ayrıca aşağıya algoritmasının Bu problem
üzerindeki başarımı da incelenmiştir.
