Depremlerin yıkıcı etkilerini azaltmak için yapılan çalışmalar, son zamanlarda üzerinde durulan araştırma konuları arasındadır. Bu çalışmada, kare, üçgen, sinüs ve daire olmak üzere dört farklı saha dizisinde çelik metamalzemeler kullanılarak titreşim etkilerini azaltmak için bir dizi simülasyon çalışmaları gerçekleştirilmiştir. Oluşan iletim kayıpları sonlu elamanlar yöntemi (FEM) kullanılarak belirlenmiştir. Simülasyon çalışmasında, çelik yapıların çap ve malzeme özellikleri ile zemin yapısı ve boyutları sabit tutulurken parametrik tanımlamalar yapılmış, kazıkların dizilişleri geometrik olarak birbirinden farklı tutulmuştur. Çalışmanın amacı, çelik için en uygun saha uygulamasını belirlemek ve saha dizilimleri sonucunda ortaya çıkan farklılıkları incelemektir. Simülasyonlar sonucunda bütün uygulamalarda yüzey titreşimlerinin 5.8 ve 8.5 Hz frekans değerlerinde önemli ölçüde kısıtlandığı görülmüştür. Ancak uygulanan saha yapıları karşılaştırıldığında, üçgen dizilimindeki sahanın diğer saha uygulamalarına göre yüzey dalgalarını daha fazla engellediği sonucuna varılmıştır.

Studies conducted to reduce the destructive effects of earthquakes are among the research topics that have been focused on recently. In this study, a series of simulation studies were carried out to reduce vibration effects by using steel metamaterials in four different field sequences: square, triangle, sine and circle. The resulting transmission losses are determined using the finite integration method (FEM). In the simulation study, parametric definitions were made while keeping the steel structures and ground constant, and the arrangement of the piles were kept geometrically different from each other. The aim of the study is to determine the most appropriate field application for steel and to examine the differences that arise as a result of the field alignments. As a result of the simulations, it has been observed that the surface vibrations are significantly restricted at 5.8 and 8.5 Hz frequency values in all applications. However, when the applied field structures were compared, it was concluded that the field in the triangular arrangement prevented surface waves more than other field applications.
