Geotechnical Design with Respect to TBDY-2018: Liquefaction and Soil-Pile -Structure Interaction Analyses

Abstract

This study explores the design steps of a building foundation in liquefiable soils according to TBDY 2018. For this purpose, geotechnical engineering design was performed in stages including the liquefaction and soil-pile-structure interaction analyses. The problematic issues such as the determination of Mw values that were used during liquefaction analyses, the search for time histories records to be scaled, the absence of recommended tolerable limits for the foundation soil settlements and different assumptions underlying the kinematic and inertial interaction approaches for Method III were addressed.

TBDY 2018'e Göre Geoteknik Tasarım: Sıvılaşma ve Yapı-Kazık-Zemin Etkileşimi Analizleri

Abstract

Bu çalışma Türkiye Bina Deprem Yönetmeliği (TBDY) 2018'e göre sıvılaşma potansiyeli olan zeminlerde derin temel tasarım adımlarını irdelemektedir. Bu amaçla, 1 Ocak 2019'dan itibaren yürürlükte olan yeni TBDY'e göre Mudanya'da inşa edilmesi planlanan bir apartman yapısının sıvılaşma ve zemin-kazık-yapı etkileşim analizleri de dahil olmak üzere geoteknik mühendislik tasarım aşamaları gerçekleştirilmiş ve sunulmuştur. Sıvılaşma analizlerindeki belirsizlikler, deprem kayıtlarının elde edilmesindeki ve ölçeklenmesindeki zorluklar, oturma sınır değerlerinin yönetmelikte belirtilmemesi ve Yöntem III'teki kinematik ve eylemsizlik etkileşimi analizi yaklaşımlarındaki farklı davranış kabullerine bu çalışmada dikkat çekilmiş ve tartışılmıştır.
