Abstract
Piles can be advantageous for construction, mainly due to strength increasing properties in foundation soils. Piles are used to support the foundations of both new structures and existing structures suffering damage. Piles are widely used in active areas, where they may have to resist significant vertical and earthquake loads. Therefore, their behaviour under vertical and eartquake load should be of interest. In this study, behavior of piles under earthquake loads were investigated using Plaxis 2D Program which employes the finite element method. In the analyses, Kocaeli earthquake vibration was applied to a sand model consisting of four piles under a certain vertical load. The piles were subjected to the same earthquake load for two different situations, striped and non- striped. According to the results of the analysis, it was determined that the acceleration values of the striped piles are lower than the piles without striped.

Abstract
Kazıklar, yapıların temel zemininde mukavemet artırıcı özellikler sağlaması açısından avantaj sağlayan bir yöntemdir. Bu yöntem, inşaat yapılması planlanan veya mevcut mühendislik yapılarının sorunlu temel zemininden dolayı zarar görmesini önlemek için kullanılmaktadır. Kazıklar, düşey ve deprem yüklerine dayanması açısından son yıllarda yaygın olarak tercih edilmektedir. Bu nedenle, kazıkların temel davranışının iyi incelenmesi önem arz etmektedir. Bu çalışmada, kazıkların deprem yükü altındaki davranışı, sonlu elemanlar yöntemini kullanan Plaxis 2D programı yardımıyla araştırılmıştır. Analizlerde dört kazıktan oluşan kum zemin modeline belirli bir düşey yük etkisinde Kocaeli deprem titreşimi uygulanmıştır. Analizlerde kazıklar kuşaklı ve kuşaksız olmak üzere iki farklı durum için aynı deprem yüküne maruz bırakılmıştır. Analiz sonuçlarına göre, kuşaklı kazık gruplarının ivme değerlerinin kuşaksız kazık gruplarına göre daha düşük olduğu belirlenmiştir.
