Outline of Final Research Achievements

After the 2011 Tohoku earthquake, the concept of unexpected ground motion caused a big issue. To respond to this difficult problem, the critical excitation methods have been developed. The concept of critical excitation and the concept of resilience of building structures have been mixed effectively and more reliable structural design methods have been developed. This new treatment enabled the design of building structures which do not deteriorate rapidly under unexpected earthquake ground motions. Furthermore the uncertainties of both input ground motions and structural parameters of buildings have been taken into account in the new structural design method.
