| Outline of Final Research Achievements |
The objective of this study is to develop a methodology for validation of analytical models for structural earthquake response analysis using high-performance computation. For this purpose, we performed a seismic response analysis of a very large analysis model and a seismic response analysis of a very large number of analysis models, and developed a methodology for validation based on these two seismic response analyses. The two analyses were successfully performed while improving the parallel finite element method used to perform the seismic response analysis. Based on the results, an analytical model validation methodology was devised to determine the failure of the analytical models and results by visualizing the principal stresses. The visualization of principal stresses is based on the curve coordinates created by smoothly connecting the directions of principal stresses, and we succeeded in deriving a boundary value problem to determine the curve coordinates.
