In this study, it is aimed to improve the performance of an existing deep excavation design of a light rail system storage facility subjected to static and dynamic loading. In this context, considering the variation of soil properties along the storage site, 6 critical cross-sections were chosen and idealized soil profiles and geotechnical design input parameters were developed. The results of 2-D finite element analyses showed that forces on diaphragm walls and box sections exceed the capacity limits consistent with the measured very low SPT-N field values of 1 blow/30 cm. Additionally, due to high ground water table, seepage-induced problems were anticipated. Base heave problems were also observed to be likely. In order to improve the performance of the system, rigid columns are planned to be constructed behind diaphragm walls. Additionally a plug under the buried box section that reduces possible artesian pressures on the excavation base, which also increases safety against seepage and uplift problems and reduces the forces on the foundation of the box section, is designed. To eliminate buckling of the strut elements, it was decided to reduce the the strut lengths by using king-post columns and permanent diaphragm walls middle of each section. Finally the performance of the overall improved system was analyzed under static and dynamic loading conditions

Vaka Analizi: Bir Metro İstasyonu Viyadük Geçiş Projesinin Sismik Zemin - Kazikli Radye Temel Etkileşimi Değerlendirmesi
Çetin, Kemal Önder; Ilgaç, Makbule; Can, Gizem (null; 2017-10-13)
Bu çalışma bir metro viyadük projesi için tasarlanan viyadük ayaklarının, kazıklı radye temel sisteminin deprem yükleri altında temel zemini ile etkileşiminin belirlenmesini amaçlamaktadır. Bildiri kapsamında öncelikle mevcut jeoteknik ve jeofizik verilerin özeti ile analizlere esas idealize zemin profili sunulacaktır. Müteakiben, sayısal modelleme çalışmasının detayları ve sonuçları sıralanacaktır. Sayısal modellemede üst yapı ile temel sistemini ayrıştırılmış analizleri sonrası sonuçların bütünleştirilmes...
COMPARATIVE ASSESSMENT OF THE SEISMIC PERFORMANCE OF FIXED BASE AND ROCKING BUILDING FRAMES EQUIPPED WITH AN ENERGY DISSIPATION SYSTEM
Özen, Hazal; Dicleli, Murat; Department of Engineering Sciences (2023-3-06)
In this study, the effect of columns with a rocking-base isolation system on enhancing the seismic performance of a reinforced concrete building is investigated. A compara- tive study comprising of comparisons of fixed-based and rocking-based systems with post-tensioning strands and free column ends is conducted. For analysis purposes, a reinforced-concrete building with shear walls was designed, modeled, and analyzed in ETABS software. Nonlinear boundary time history analysis (NTHA) was conducted by exposi...
Mixed mode fatigue crack growth path and life prediction under variable amplitude loading through extended finite element method
Dirik, Haydar; Yalçınkaya, Tuncay; Department of Aerospace Engineering (2017)
The main purpose of this study is to predict the crack growth path trajectories and fatigue crack growth (FCG) life under variable amplitude loading (VAL) by using Extended Finite Element Method (XFEM). For this purpose a computational algo- rithm is developed in Fortran which interacts with a commercial finite element soft- ware (Abaqus) and automatically propagates cracks which is initially modelled as stationary crack. Nasgro FCG equation is used for FCG life calculation which has a great accuracy among t...
