Özet
While evaluating the seismic performance of existing buildings according to TBC2018, a difficulty and complexity arouses in estimating the rotations that occur at both ends of the load carrying elements under seismic forces. Therefore, in this study, it is aimed to develop a reliable method for estimating the seismic performance of reinforced concrete (RC) buildings using simplified displacement-based formulations. Within the scope of this study, 4 RC buildings having same symmetrical floor plan but with varying number of stories, different material strengths were designed, and 3 existing RC buildings were taken into consideration. All the 7 buildings were modeled using common structural analysis software like SAP2000v20, Sta4CADv14.1, & Idot;deCADv10 and ProtaStructure2022 and linear seismic performance analysis were performed. The data obtained as a result of the analysis were processed into the displacement-based formulations created within theframeworkof this study to determine the damage state of the columns and associated seismic performance of the existing RC buildings considering the general principles and rules given in TBC2018. It was determined that the compatibility between the column damage conditions determined according to the proposed method and the column damage status determined as a result of the hand calculation made according to the calculation principles specified in TBC2018 was 100% in both principal directions. In addition, it is found that the resultsfoundfrom the proposed method were conservative and generally compatible with the results obtained from the common structural analysis software.
