“…There are many studies examining the changes between the last two regulations. In these studies, earthquake force calculation methods, base shear forces, displacements, period, target displacements, spectrum curves and section damage values were examined and compared Aksoylu et al, 2020;Aksoylu and Arslan, 2021;Keskin and Bozdoğan, 2018;Koçer et al, 2018;Bozer, 2020;Ulutaş, 2019;Adar et al, 2021;Seyrek, 2020;Büyüksaraç et al, 2021;Başaran, 2018;Nemutlu and Sarı, 2018;Işık et al, 2021a;Yalın and Ulutaş, 2021;Peker ve Işık, 2021;Akyıldız et al, 2021). In the study conducted by Başaran and Hiçyilmaz (2020), the effects of different earthquake ground motion levels on reinforcedconcrete frames were examined.…”
