Determination of the change in the structural performance of an RC building due to a nearby deep excavation
Mangır, Atakan; Coşgun, Turgay; Sayın, Barış; Okumuş, Vefa; Güneş, Barış (Elsevier Ltd, 2023)In this study, the structural performance of an existing thirteen-story reinforced concrete building is evaluated and compared to the case caused by the ground motion due to a nearby deep excavation. Accordingly, the effects ... -
Experimental behaviour and failure of beam-column joints with plain bars, low-strength concrete and different anchorage details
Coşgun, Cumhur; Türk, Ahmet Murat; Mangır, Atakan; Coşgun, Turgay; Kıymaz, Güven (Pergamon-Elsevier Science Ltd, 2020)In framed structures, both steel and reinforced concrete, beam-column joints play a very crucial role in terms of seismic resistance. Under the effects of high lateral seismic loads, beam-column joints are subjected to ... -
Fuzzy Inference System (FIS) model for the seismic parameters of code-based earthquake response spectra
Mangır, Atakan (Multidisciplinary Digital Publishing Institute (MDPI), 2023)The response spectra defined in seismic design codes include crisp classifications of seismic parameters, which directly affect the spectra’s shape and greatly alter seismic design loads. The optimum design phase seismic ... -
Innovative equivalent elastic modulus based stress calculation methodology for reinforced concrete columns
Şen, Zekai; Mangır, Atakan (MDPI, 2023)The combination of linearity and elasticity assumptions provides classical calculation procedures for the reinforced concrete (RC) columns and beams against internal and external seismic loads. In these calculation procedures, ... -
Pre-earthquake fuzzy logic-based rapid hazard assessment of reinforced concrete buildings
Mangır, Atakan; Okumuş, Vefa (Elsevier Ltd, 2023)The main purpose of this paper is to present a rapid building assessment fuzzy logic (FL) modelling for risk assessment based on expert construction engineering verbal informatics. Before an earthquake, a set of input ... -
Retrofitting technique effectiveness and seismic performance of multi-rise RC buildings: A case study
Çoşgun, Turgay; Sayın, Barış; Güneş, Barış; Mangır, Atakan (Elsevier Ltd, 2022)This study aims to determine the effectiveness of a retrofitting technique based on the seismic performance analysis results comparison between two inactive multi-storey reinforced concrete (RC) buildings for a long period. ... -
Seismic assessment of a reconstructed historic masonry structure: A case study on the ruins of Bigali castle mosque built in the early 1800s
Güneş, Barış; Coşgun, Turgay; Sayın, Barış; Ceylan, Oǧuz; Mangır, Atakan; Gümüşdağ, Gökhan (Elsevier Ltd, 2021)Architectural and cultural heritage structures that have provided important services in the past may lose their functions over time and become out of service due to possible reasons. The loss of the structural integrity ... -
Seismic load tests on exterior beam-column connections of existing RC structures
Coşgun, Turgay; Coşgun, Cumhur; Kaniskha, Abdulrauf; Mangır, Atakan; Sayın, Barış; Türk, Ahmet Murat (Croatian Soc Civil Engineers, 2019)Recommendations for enhancement of performance of RC beam-column joints under seismic effects are presented in this study. The aim is to evaluate the use of low-strength concrete with plain bars without stirrups in the ... -
Seismic performance assessment of a historical masonry-infilled RC building located in the historical peninsula of Istanbul (1940s)
Güneş, Barış; Mangır, Atakan; Çoşgun, Turgay; Sayın, Barış; Akçay, Cemil (Elsevier Ltd, 2022)The current paper presents a seismic performance evaluation methodology for masonry-infilled RC buildings based on nonlinear analyses. The entire process is illustrated using a case study of a university building constructed ... -
Seismic performance of an existing low-rise RC building considering the addition of a new storey
Güneş, Barış; Coşgun, Turgay; Sayın, Barış; Mangır, Atakan (Pontificia Universidad Católica de Chile, 2019)In low-rise reinforced concrete (RC) buildings, structural design is generally performed considering the seismic effects as well as the vertical loads. However, there may be situations where the additional or unpredicted ...
