| Outline of Final Research Achievements |
In the current design system, there are two important problems to be solved. The one is evaluation of a margin of safety to the ultimate limit state as collapsing or overturning. The other is considering uncertainty in the natural disturbance as earthquakes. To solve the problems, we studied with close cooperation about (i) elasto-plastic instability, (ii) combined geometric and material nonlinear analysis, (iii) degradation behavior of structures, and (iv) robust design optimization under uncertainty. We obtained theoretical and experimental results about deformation concentration phenomena and its suppression methods.
