Student, Civil Engineering Department, Qom University of Technology, Qom, Iran Journal Article 2024 07 07 This study investigates the seismic active pressure induced by the Kahramanmaraş earthquake in Türkiye that occurred on February 6, 2023, with a magnitude of  7.7, using a time-domain pseudo-dynamic approach. This methodology enables the incorporation of actual ground motion data from the earthquake into the analysis. Morever, it employs a momentum theory-based technique to precisely identify the critical failure surface. Seismic accelerations recorded at four specific stations located 14, 123, 142 and 237 km away from the earthquake's epicenter, experiencing peak ground accelerations of 0.57<em>g</em>, 0.15<em>g</em>, 1.34<em>g</em> and 0.17<em>g</em> respectively, are utilized to evaluate the seismic active pressure acting on a retaining wall. The results indicate that the proposed approach yields more realistic outcomes compared to conventional methods, particularly in scenarios of significant earthquakes. Besides the peak ground acceleration of the earthquake, which influences the active seismic pressure, the frequency content of the earthquake, and the site's position relative to the fault movement also play crucial roles. https://www.jsee.ir/article_714381_d6195c052e42ec9755e9f3943d292ce3.pdf
