This study investigates the seismic resilience of an existing RC (Reinforced Concrete) dual-system designed according to the Turkish guidelines (TEC 2007) during the 2023 Kahramanmaraş earthquakes. The shear wall-frame dual building experienced negligible damage during earthquakes, whereas all neighboring buildings collapsed. The 3D building model was subsequently subjected to pushover and nonlinear time-history analyses (NTHA) using the real ground motions recorded during the Pazarcik earthquake (𝑀𝑤=7.7). The results from the NTHA indicate that the maximum inter-story drift (IDR) ratios on all floors of the case study building remained below the Immediate Occupancy performance level (IDR = 1%). Moreover, the dual-system buildings designed with TEC 2007 survived the earthquakes without damage, even if the design earthquake scenarios exceeded those considered in the more stringent new TBEC 2018 (i.e., 475 return period). The limited damage experienced by the RC dual-system building can be largely attributed to its high wall index (ρ=1.5% and 1.95%) and high average lateral stiffness index (H/T ≥ 44), which are above the minimum values (ρ=0.6% and H/T ≥ 45) suggested in previous studies. This study contributes to a better understanding of the resilience of RC shear wall-frame buildings in seismic zones.
