Abstract

In this paper, elastic and/or visco-elastic two dimensional and axially symmetric Soil-Structure Interaction (SSI) problems are investigated by using finite and infinite elements. By this model, problems are analysed by discretizing the near field with four-noded linear or eight-noded quadratic finite elements and the far field extending to infinity with infinite elements. In the case of harmonic loading the formulation is performed in complex domain. The results of several sample problems obtained by the proposed model in this study are compared with those available in the literature or exact results.

Özet

Bu çalışmada, elastik ve/veya viskoelastik iki boyutlu ve eksenel simetrik yapı-zemin etkileşimi problemleri harmonik yükleme altında, yapıya yakın bölgelerde sonlu eleman, uzak bölgelerde ise sonsuz elemanlar kullanılarak incelenmiştir. Harmonik yükleme halinde çözüm kompleks uzayda yapılmıştır. Yakın bölgenin modellenmesinde, 4 düğümlü lineer veya 8 düğümlü kuadratik eleman kullanılmıştır. Sonsuz eleman olarak ise, seçilen sonlu elemana uyumlu, azalan fonksiyonlu ve dalga karakterini içeren elemanlar kullanılmıştır. Sonlu-sonsuz eleman modeli kullanılarak elde edilen sonuçlar, analitik veya başka yöntemlerle elde edilen sonuçlar ile karşılaştırılmıştır.
