Abstract

Günümüz ihtiyaçlarına cevap veremeyen yapıların yenilenmesi, doğal afetler, bölgesel ve küresel savaşlar sonucunda önemli oranda inşaat ve yıkıntı atığı malzeme ortaya çakmaktadır. Ortaya çıkan bu atıkların dönüştürülerek tekrar kullanılması yoluyla bertaraf edilmesi son yılların en önemli araştırma konularındandır. İnşaat ve yıkıntı atığı malzemeler dönüştürülerek geri dönüşümlü agregalar elde edilmektedir. Geri dönüşümlü agreganın sürdürülebilir bir ürün olarak yeni beton üretiminde veya zemin dolgusu olarak kullanılması için detaylı çalışmalar yapılmış ve bu çalışmaların kapsamı genişleyerek devam etmektedir. Bu çalışma kapsamında ise hem üst yapıyı temsil eden sürekli temel kirişi hem de temelin altındaki dolgu zeminin sürdürülebilir malzemelerle üretildiği varsayılan yapı zemin etkileşim problemi incelenmiştir. Çalışma kapsamında üst yapıyı temsil eden sürekli temel kirişinin beton özellikleri konvansiyonel ve sürdürülebilir betonla dikkate alınmıştır. Zemin dolgusunun karakteristik özellikleri ise beş farklı sürdürülebilir malzeme ile dikkate alınmıştır. Yapılan nümerik simülasyonla, temelde meydana gelen çökme, dönme, eğilme momenti, kesme kuvveti ve yay kuvvetleri elde edilmiştir. Sürdürülebilir yapı-zemin etkileşim problemi için elde edilen bu sonuçlar, konvansiyonel yapı-zemin etkileşim probleminden elde edilen sonuçlarla kapsamlı olarak karşılaştırılmıştır. Yapılan karşılaştırmalardan elde edilen sonuçlara göre temelde meydana gelen çökme, dönme, eğilme momenti, kesme kuvveti ve yay kuvvetlerinin sürdürülebilir malzeme özelliklerinden belirli oranda etkilendiği görülmüştür.

The Behavior of Continuous Foundations with Sustainable Concrete and Soil Under Monotonic Loads

Abstract

Due to the renovation of structures, natural disasters, and regional-global wars, construction and demolition waste material is generated. The remediation of these wastes by recycling and reusing activities is one of recent most common research topics. Recycled aggregates are obtained through the recycling activities of these waste materials. In the literature, detailed studies have been carried out to use recycled aggregate as a sustainable product in producing new concrete or as a filling material. Besides, the scope of these studies continues to expand. In this comprehensive study, the structural behavior of the soil-structure interaction problem under the monotonic load, which is assumed to be produced with sustainable materials, was investigated. Furthermore, the concrete properties of these foundation beams representing the superstructure were considered with conventional and sustainable concrete. The characteristics of the filling materials were regarded with five different sustainable materials. The deflection, rotation, bending moment, shear force, and spring forces are obtained based on the numerical simulation. The sustainable soil-structure interaction problem results were compared with the conventional counterparts. Based on the comparisons, it was observed that the deflection, rotation, bending moment, shear force, and spring forces that occur in the foundation beam are affected by sustainable material properties.
