Traditional seismic hazard analyses underestimate hazard levels when compared to observations from the 2023 Kahramanmaras earthquakes Altindal, Abdullah; Askan Gündoğan, Ayşegül (2024-12-01) A sequence of two major earthquakes, Mw7.8 Pazarcik, and Mw7.5 Elbistan, struck Southeastern Turkey in February 2023. The large magnitudes of the earthquakes and the short time between the two events raised questions about...
A Numerical Investigation of Longitudinal Track–Bridge Interaction in Simply Supported Precast Concrete Girder Railway Bridges Ozturk, Alper; Baran, Eray; Askan Gündoğan, Ayşegül (2024-08-01) In railway tracks, additional stresses occur in rails due to interaction between the rail and the bridge superstructure, which is a phenomenon known as track–bridge interaction (TBI). The additional rail stresses (ARSs) de...

Effect of Wall Size on the Rotation Capacity of Reinforced Concrete Structural Walls Kazaz, İlker; Sertkaya, Mahinur; Yakut, Ahmet (2024-04-01) The limiting deformations of RC members used in seismic design and assessment are mainly based on experimental measurements, for which the lack of structural wall tests of large sizes restricts our knowledge on the deforma...
Using System Dynamics to Support Strategic Digitalization Decisions Kaya, Hazal Deniz; Dikmen Toker, İrem (2024-04-01) Although digitalization has become a prospect that is counted on for many problems in the construction industry, there have been limited attempts at exploring decision-making processes in construction firms concerning the ...
Liquefaction and performance of foundation systems in Iskenderun during 2023 Kahramanmaras-Turkiye earthquake sequence ÖZENER, Pelin; Monkul, M. Murat; Bayat, Esra Ece; ARİ, Abdulmuttalip; Çetin, Kemal Önder (2024-03-01) On February 6, 2023, two devastating earthquakes occurred on the East Anatolian Fault, Turkiye. The earthquakes had severe impacts on civil engineering structures in Iskenderun, Hatay. Reconnaissance studies were performed...
Real options valuation of photovoltaic investments: A case from Turkey Or, Bartu; Bilgin, Gozde; Akcay, Emre Caner; Dikmen, Irem; Birgönül, Mustafa Talat (2024-03-01) Investments in renewable energy resources have become inevitable due to increasing energy demand and energy prices, diminishing non-renewable energy resources, and the outgrowth of carbon footprints. Photovoltaic (PV) syst...
Local site effects at the selected stations affected by the February 6 2023 Türkiye Earthquake Sequences İLHAN, OKAN; Indır, Onur; Muratoğlu, Gamze; İçen, Abdullah; Albayrak, Kubilay; SANDIKKAYA, MUSTAFA ABDULLAH; Askan Gündoğan, Ayşegül; Arduino, Pedro; Taciroğlu, Ertuğrul (2024-03-01) This paper explores the applicability of one-dimensional (1D) nonlinear (NL) and equivalent-linear (EL) site response analyses (SRA) for characterizing site effects at selected strong ground motion stations impacted by the...
Geospatial Liquefaction Modeling of the 2023 Türkiye Earthquake Sequence by an Ensemble of Global, Continental, Regional, and Event-Specific Models Asadi, Adel; Sanon, Christina; Çakır, Elife; Zhan, Weiwei; Shirzadi, Hooman; Baise, Laurie Gaskins; Çetin, Kemal Önder; Moaveni, Babak (2024-03-01) A global geospatial liquefaction model (GGLM-2017) was previously developed (Zhu et al., 2017) using logistic regression (LR) and is currently used by the U.S. Geological Survey as the preferred liquefaction model to map l...
Duration Characteristics of Strong Ground Motions Recorded during the 6 February 2023 M 7.8 Pazarcık, Kahramanmaraş, Türkiye, Earthquake Elsaid, Alaa; Çetin, Kemal Önder (2024-03-01) The seismograms recorded at a total of 71 strong ground-motion stations (SGMS) located within 100 km of the fault rupture were used to investigate the durational variability observed during the 6 February 2023 M 7.8 Pazarc...
