The commonly used spectrum analysis methods are summarized and their problems are analyzed. In this paper; the time-domain response spectrum is first analyzed and the frequency-domain normalized spectrum is given. The normalized time-frequency response spectra are calculated and compared by four typical ground vibration waveforms. This project will use the standardized time-frequency response spectrum analysis method to analyze the susceptibility of impact ground shaking and ground motions containing rich high-frequency components to structural damage under the action of strong earthquakes. The results show that the method can better reflect the ground shaking response characteristics and the damage mechanism of the structure. The model also reflects the role of seismic calendar time on the cumulative damage of buildings. © 2024 International Association for Housing Science. All rights reserved;
