Yapı zemin etkileşimi yapıların deprem etkileri altındaki davranışlarının doğru olarak belirlenmesinde önemli rol oynamaktadır. Geleneksel tasarım çalışmalarında yapının tabandan ankastre olduğu kabulü sıklıkla kullanılmakta ve yapı-zemin etkileşimi dikkate alınmamaktadır. Bununla birlikte, özellikle esnek zemin ortamlarında bulunan tarihi yığma yapılarda deprem yer hareketleri yapı davranışını önemli derecede etkileyebilmektedir. Bu çalışmada, tarihi yığma bir minarenin esnek ve ankastre mesnetlenme durumları için deprem davranışları, yatay ve yatay+düşey yer hareket bileşenleri için araştırılmaktadır. Çalışmada, kayma dalgası hızları sırasıyla 1000, 270 ve 90 m/s olan üç farklı zemin türü kullanılmıştır. Üç boyutlu sonlu eleman modelinin oluşturulmasında minarede tetrahedral, zemin ortamında hexahedral sonlu ve sonsuz elemanlar kullanılmıştır. Oluşturulan sonlu eleman modeli, Operasyonel Modal Analiz Yöntemi deneysel sonuçlarına göre kalibre edilmiştir. Kalibre edilen sonlu eleman modeli kullanılarak minare-zemin etkileşim sisteminin yatay, yatay+düşey yer hareketleri altında lineer deprem davranışları, farlı zemin ve ankastre mesnetlenme durumları için elde edilerek karşılaştırılmıştır.
