RAO_1 OPTİMİZASYON ALGORİTMASI KULLANILARAK TABAN PLAĞI DİŞLİ BETONARME KONSOL İSTİNAT DUVARI TASARIMI

Bu çalışmada, düşük ağırlığa sahip, tabanında diş kesit bulunan betonarme bir konsol istinat duvarı tasarımı optimizasyonu konu edilmiştir. Optimizasyon süreci için, daha önce istinat duvarı problemine uygulanmamış bir algoritma olan Rao_1 algoritması kullanılmıştır. İstinat duvarı optimizasyonunda, problemi tanımlamak için 12 tasarım değişkeni ve 26 kısıt kullanılmıştır. Tasarım, Rankine yanal basınç teorisi yardımıyla, duvarın geoteknik stabilitesini korumak amacıyla duvarın kayma, dönme ve temelin taşıma gücüne karşı güvenlik katsayıları ile sınırlandırılmıştır. Betonarme tasarımın iç stabilitesini sağlamak üzere moment ve kayma kapasitesi için ACI 318-05 standardından faydalanılmıştır. Tasarım, taban plağı dişli ve dişsiz konsol istinat duvarları olan iki ayrı sayısal örnekle desteklenmiştir.

Reinforced Concrete Cantilever Retaining Wall with the Shear Key Design by Using Rao_1 Optimization Algorithm

In this study, low-weight reinforced concrete retaining wall with the shear key design optimization is subjected. For optimization process, Rao_1 algorithm, which was not implemented to the retaining wall problem before, is used. Twelve design variables and twenty-six constraints, which were constituted in order to define the problem, were used for retaining wall optimization. The design is restricted with the purpose of preserve the geotechnical stability of the wall with the safety factors against to sliding, overturning and bearing capacity failure modes by the help of the Rankine theory for lateral earth pressure. In order to provide internal stability of the wall for moment and shear capacity, it is utilized from ACI 318-05 standards. The design was supported with 2 different numerical examples, which they are the cantilever retaining wall with the shear key and without shear key
