[S01A-05] Fundamental study on development of data driven earthquake response analysisconsidering geotechnical engineering knowledge
Keywords:Dynamic Mode Decompsition, Ground response analysis
The authors address at performing ground response analysis using Dynamic Mode Decomposition (DMD). In this study, we attempt to utilize geotechnical engineering knowledge into DMD analysis algorithm by interpreting the physical meaning of the time transition matrix A obtained from DMD analysis. In order to consider the nonstationary of the input seismic motion, we implemented DMD-C which extended the algorithm of DMD for ground response analysis. Finally, we applied this method to a simple example of one-dimensional ground response analysis and verified its effectiveness.
