Özet: In recent years, in order to determine the structural performance of existing buildings under earthquake effect, instead of force-based methods, non-linear methods based on the change of deformation and displacement have been started. Turkish Building Earthquake Code (TBDY-2018) and Specification for Buildings to be Built in Seismic Zones (DBYBHY-2007), both proposes linear and non-linear calculation methods in order to determine performances of existing buildings. Non-linear analysis methods proposed by TBDY-2018 are; Single Mode Pushover, Multi-mode Pushover and Time History analysis. Non-linear analysis methods proposed by DBYBHY-2007 are; Incremental Equivalent Earthquake Load Method, Incremental Modal Superposition Method and Non-linear Time History analysis. The major difference between TBDY-2018 and DBYBHY-2007 is the description of the effective cross section stiffness and damage limits of reinforced concrete sections. In this study, the  performance analysis of the structural system under earthquake loads by using non-linear incremental pushover analysis according to DBYBHY-2007  and TBDY-2018 have been performed for existing five storey reinforced concrete residential structure and results have comparatively been discussed.
