Nonlinear time-history analysis of a steel-reinforced concrete composite building according to TBDY-2018

Turkey is recognized as one of the most seismically active regions in the world. The 1999 İzmit, 2011 Van, 2020 İzmir, and 2023 Kahramanmaraş earthquakes are among the significant seismic events in recent years that have resulted in substantial losses. These earthquakes have revealed that a large portion of the building stock in our country is vulnerable to earthquakes. Chapter 15 of the Turkish Building Earthquake Code-2018 includes guidelines for evaluating existing building systems under seismic effects. In this study, the earthquake performance of a composite building consisting of reinforced concrete shear walls and steel frames was examined using a nonlinear time-history analysis method in line with the specified rules and calculation principles. Eleven real earthquake records were selected, scaled, and used for the nonlinear time-history analyses. The building under investigation is located in the İskenderun district of Hatay province, and it sustained no damage during the February 6, 2023, Kahramanmaraş earthquakes and is currently in active use. In the final section of the thesis, ground motion records from the February 6, 2023 Pazarcık (7.7 Mw) earthquake were obtained from two different stations and applied to the building model and the results obtained from the analyses were then examined.
