| Outline of Final Research Achievements |
It is very important for the structural design of buildings to estimate accurately the behavior of not only the upper structure but also the underground structure including piles during severe earthquakes. Although many simulation analysis and behavior estimation have been done based on the seismic observation records, the study is not enough especially for the underground structure. We performed the simulation analyses of the soil-foundation-structure system based on the observed records using the detailed 3-dimensional FEM model, and confirmed that the accuracy of the analysis result including the underground structure is high.
In this study, simulation analyses using 3-dimensional FEM model using input motion beyond the design level earthquake were carried out, then the ultimate behavior of buildings was estimated.
