It is well established that pulse-like ground motions typically exhibit distinct characteristics that can substantially influence the seismic demands on structures. During the 2023 Kahramanmaraş earthquake, numerous pulse-like ground motion records were collected from various seismic stations. In this study, the elastic input energy spectra are computed for 5% damping considering the selected pulse-like ground motion records of the 2023 Kahramanmaraş earthquake. Subsequently, the inelastic input energy spectra of these records are computed for the same damping, considering the specific hysteretic model used in the analysis. A comparison of the inelastic input energy demands on single-degree-of-freedom (SDOF) systems subjected to the selected pulse-like ground motions is presented for various ductility ratios. The ratios of inelastic energy spectral ordinates to elastic energy spectral ordinates are then compared graphically. It is observed that as the ductility ratio increases, the ratio of inelastic to elastic input energies begins to decrease, because inelastic input energy tends to diminish with higher ductility ratios. The results are presented graphically for the selected pulse-like ground motions from the 2023 Kahramanmaraş earthquake, revealing fluctuations around the ratio of 1.0 across different periods.
