Abstract: The real earthquake characterization is essential for better understanding wave acceleration phenomena and the characterization of the Bhuj and Kobe subject to earthquake excitations. Results of ongoing time-frequency research are presented here with the aim to compare the performance of various state-of-the-art time-frequency distributions when applied to earthquake records to the Irregular and Regular building. In a near future, the objective is to adopt this innovative joint time-frequency signal processing technique to earthquake record analysis and parameter estimation. The time-frequency distributions studied are the acceleration, velocity and Displacement. The earthquake records ranging from strong to medium soil condition, where used in this analysis. These accelerogram time series were recorded in the Kobe and Bhuj earthquake time history records applied to medium soil condition for frequency and time domain analysis. Based on our results, is our comparison between two earthquake frequency and time domain applied to Irregular and Regular shape building. The ETAB software is used to analyze the Irregular and regular building for the G+15 storey.
