Abstract: Turkey earthquake on February 6, 2023, shows greater destructiveness and the acceleration response spectrum far exceeds the highest design standard of the Chinese seismic code. Therefore, it is necessary to study whether the base-isolated structure based on the Chinese code can maintain good seismic performance under the Turkey earthquake. In this study, the 6-story, 8-story and 10-story base-isolated structures using lead rubber bearings and based on the direct design method proposed in the Standard for Seismic isolation design of building (GB/T 51408−2021) are taken as the research object. The Turkey earthquake records and 22 ordinary far-field earthquakes are taken as excitation inputs for extensive parameter research. The parameter analysis results show that the base-isolated structure based on Chinese code remained in a safe state under 22 far-field earthquakes. Meanwhile, a considerable part of the base-isolated structure will be severely damaged under the Turkey earthquake. Besides, the base-isolated structures with a larger isolation system period have better seismic performance. However, the floor acceleration cannot be effectively controlled for base-isolated structures with a larger yielding strength of the isolation system.
