Outline of Final Research Achievements

In order to appropriately take into account of uncertainties in seismic inputs for building structures. We have presented an approximately worst-case method based on order statistics. By theoretical analysis of the distribution-free tolerance interval, we could obtain the relationship between prediction accuracy and sample size to the uncertainties in the seismic design of buildings. On the basis of the method, we have also proposed a multiobjective optimization approach for robust seismic design, which enables to control the seismic robustness of building structures. Furthermore, we integrated the elemental technologies and developed a numerical-experimental system for robust seismic design. By application of the system to seismic design of building structures, we examined the effectiveness of the approach and what structure has the high seismic robustness. By the numerical results, we have concluded the displacement-restraint brace structure could improve the seismic robustness.
