| Outline of Final Research Achievements |
In this study, Evaluation method of seismic responses of the building supported by piles during large earthquake and indicators for post earthquake functional use of the building are investigated based on earthquake damage cases. The main results are as follows; First, simulation analyses of the building that was damaged at the pile foundation by earthquakes are conducted and the analysis model that can evaluate the damage of the pile foundation is built. Next, the parametric studies based on the model that is well simulated the earthquake damage shows the possibility of estimating the damage of the pile foundation using the information obtained from the strong motion observation records. Finally, model tests are conducted on useful repair method to ensure the post earthquake functional use of a building supported by piles, and it is confirced that piles in ground is effective in preventing the inclination of the building.
