“…e genetic algorithm (GA) is one of the most successful techniques used due to its simplistic design and ease of application. In case of retaining walls, multiple studies have either successfully applied the GA to obtain optimized designs or have used GA for comparative analysis(Purohit [21], Naeem[22], Rahbari[23], Schmied and Karlsson[24], Pei and Xia[28], Papazafeiropoulos et al[29], Yücel et al[33], Chau and Albermani[35], Kaveh et al[47], Gandomi et al[61], Rahbari et al[64], Kayhan and Demir[66], Kalateh-Ahani and Sarani[68], Mergos and Mantoglou [77], Kalemci et al [78], Ravichandran et al[84], Mevada et al [88], Dodigović et al…”

The booming growth of computational abilities in the 21st century has led to its assimilation and benefit in all horizons of engineering. For civil engineers, these advancements have led to groundbreaking technologies such as BIM, automation, and optimization. Unfortunately, even in an era of dwindling resources and dire need for sustainability, optimization has failed to attract implementation in practice. Despite an exponential growth as an area of research interest, the optimization of engineering structures such as reinforced concrete (RC) is still a complex task that requires multidisciplinary knowledge, hindering its practicability. Although past review papers have delved into this topic, they have only been able to cover the breadth of information available by covering broader aspects of optimization of structures. This study on the other hand aims to cover this topic in depth to uncover problem specific trends and issues, by focusing only on optimization of RC cantilever retaining walls. Although there is an abundance of research studies on this topic, there is an absence of any critical review to tie them up, and concurrently with its broader scope, it suffers the same lack of applicability in the field. The in-depth review presents a summarization of all the online publications including research articles, conference papers, and theses to the best of authors’ knowledge on the topic of RC cantilever retaining wall optimization. Geographical trends, regional developments, and prominent journals have been identified. The design codes, problem formulation, objectives, constraints, variables, and their optimization techniques are tabulated for ease of understanding. Unique areas of development investigated by the different researchers have been highlighted. Lastly, comprehensive recommendations for future works have been detailed with a focus on improving its applicability and assimilation into the construction industry.

Optimum the cantilever retaining wall design for different soils and dynamic earthquake effects is presented here. In the investigation of optimum wall design-based metaheuristic, the harmony search algorithm was considered for different design cases which include five soil and two earthquake characteristics. Earthquake characteristics of mild and severe were obtained regarding two locations which was selected from Turkey Earthquake Risk Map. For selected two locations and local soil classes, map spectral acceleration coefficients were utilized defined in Turkish Building Earthquake Code-2018. Sliding, overturning, and bearing capacity safety factors were taken as design constraints for checking stability criteria of the cantilever retaining wall which is given in Turkish Building Earthquake Code-2018. Since the cost-based wall weight of the optimization problem was taken as the objective function, obtained optimum wall dimensions which are discrete design variables were compared in terms of different design cases. It is seen that the wall dimensions increase in order to meet the design criteria in case of the earthquake load increases when the obtained optimum design by the optimization analyzes are examined. Another result obtained for the same earthquake zone is that the wall dimensions and therefore the cost mostly increase in weak quality soils.

ÖzGeoteknik mühendisliğinde iki farklı zemin seviyesi arasında meydana gelen yatay kuvvetlerin stabilitesinin sağlanmasında dayanma duvarları oldukça yaygın kullanılan bir çözümdür. Bu çalışmada Türkiye Deprem Yönetmeliği 2018' e göre konsol dayanma duvarının optimum tasarımı modifiye arı kolonisi algoritması kullanılarak araştırılmıştır. Doğadan esinlenerek geliştirilen yapay arı kolonisi algoritması, arıların besin kaynağı bulma sürecini taklit eden bir sezgisel optimizasyon yöntemidir. Konsol dayanma duvarının optimum tasarımlarını elde etmek için optimizasyon analizleri yapılmış ve amaç fonksiyonu konsol dayanma duvarının maliyeti olarak alınmıştır. Duvarın geometrisinden kaynaklanan boyut limitleri, statik ve dinamik yükler etkisinde kayma, devrilme ve taşıma gücü kontrollerinin normalize edilmiş matematiksel ifadeleri algoritmaya sınırlayıcılar olarak eklenmiştir. Optimizasyon analizlerinde, temelin ön ve arka ampatman mesafeleri, gövdenin alt ve üst genişlikleri ve temel kalınlığı ayrık tasarım değişkeni olarak dikkate alınmış ve bu ayrık tasarım değişken değerleri kullanılarak tasarım kümesi oluşturulmuştur. Seçilen bölgelere göre Türkiye Deprem Haritası' ndan alınan farklı kısa periyot harita spektral ivme katsayıları ve farklı yerel zemin sınıfları için modifiye yapay arı kolonisi algoritması ile optimize edilmiş konsol dayanma duvarının minimum maliyetleri elde edilmiştir. Amaç fonksiyonunun minimum değerleri çeşitli zemin özellikleri ve deprem yüklerini içeren farklı tasarım durumları açısından karşılaştırılmıştır. Farklı tasarım durumları dikkate alınarak elde edilen optimum sonuçlar incelendiğinde değişen özelliklerin optimum tasarıma etkisi sezgisel optimizasyon analizleri ile mantıklı olarak kısa zamanda elde edilmiştir. Modifiye yapay arı kolonisi algoritmasının konsol dayanma duvar tasarımı gibi çok bilinmeyenli karmaşık mühendislik problemlerinin çözümünde etkili ve başarılı bir yöntem olduğu görülmüştür.
