Abstract

Bu makalede, Abaqus/СAЕ kullanılarak çok tabakalı bir temel zemin üzerine inşa edilmiş yapıya zemin özelliklerinin ve depremlerin etkisi incelenmiştir. Tekil temeller, depreme eğilimli bölgelerdeki binaları desteklemek için geleneksel olarak gerekli olan en yaygın temel türlerinden biridir. Çoğu araştırmacı, deprem türü ve zemin tabakasının özelliklerinden dolayı deprem sırasında binanın tepkisini etkileyebilen temel ve zemin arasındaki dinamik etkileşim üzerinde çalışmaktadır. Bu çalışmada, çok farklı zemin özelliklerine sahip iki tabakalı zeminlerde inşa edilen betonarme bir binaya dört farklı deprem uygulanmış ve Abaqus yazılımı kullanılarak zemin-yapı etkileşimi üzerine tartışma yapılmıştır. Analizde 4 farklı model (yumuşak-sert, sert-yumuşak) ile katmanlı bir zemin simüle edilmiştir. Analizlerde farklı zemin katmanlarının (yumuşak ve sert) etkisi, binanın yer değiştirmesi ve depremin frekans içeriği incelenmiştir. Elde edilen sonuçlar, dinamik zemin-yapı etkileşiminde deprem özellikleri, zemin özellikleri ve temel tipinin birlikte dikkate alınmasının oldukça önemli olduğunu göstermiştir.

A simulation on soil structure interaction with ABAQUS; effect on the behavior of a concrete building of soil layers and earthquake properties

Abstract

In this article, the effect of soil properties and earthquakes on a structure built in a multi-layer foundation soil is studied using Abaqus/СAЕ. Single foundations are one of the most common types of foundations traditionally required to support buildings in earthquake-prone regions. Most researchers work on the dynamic interaction between the foundation and the soil, which can affect the response of the building during earthquakes due to the type of earthquake and the properties of the soil layer. In this paper, four different earthquakes were applied to a reinforced concrete building constructed in two-layer soils with very different soil properties, and a discussion on soil-structure interaction was opened using Abaqus software. In the analysis, a layered soil is simulated with 4 different models (soft-hard, hard-soft). Through these analyses, the influence of the different soil layers (soft and hard), the building displacement and the frequency content of the earthquake were studied. According to the result of the analysis, it is important to consider the earthquake characteristics, the soil properties, and the type of foundation in the dynamic soil-structure interaction.
