Seismic performance evaluation of a multi-storey RC building by nonlinear static pushover and time history analysis

In the seismic zones of the world, damages caused by earthquakes at a level that can not be overlooked. Turkey is also one of in that zones and earthquakes which are occured recently have confirmed this situation. To prevent the casualities and econonomical loss due to earthquakes, seismic codes were developed and in Turkey, currently (Deprem Bölgelerinde Yapılacak Binalar Hakkında Yönetmelik - DBYBHY 2007) has been used. Türkiye Bina Deprem Yönetmeliği - TBDY 2016 was prepared and published as a draft to improve existing regulations in line with the information obtained through the studies have been made. There are two main approaches of designing earthquake resistant buildings in this draft code. These are strength based design with linear behaviour assumption and deformation and displacement based design which also considers nonlinear behaviour. In strength based design nonlinear response of materials and second order effect are not considered which causes limited information about structural performance during an earthquake. In this study, nonlinear behaviour of a multi-storey reinforced concrete building is examined with pushover and time history analysis according to TBDY 2016 draft code. In the first chapter, the purpose and scope of this study were explained. The second chapter includes earthquake-resistant structural design which are elastic design and capacity design. The third chapter gives information on the concept of performance from the point of view of TBDY 2016 draft code. The fourth chapter is about the studied building. General information was given such as the height, structural plan, purpose of use, ground type and seismicity class. The fifth chapter is about the results of the nonlinear static pushover and nonlinear time history analyses and comparison of them.
