| Research Abstract |
Because super high-rise buildings in mega cities in Japan have never been shaken intensively by earthquake ground motions after their construction, the response of high-rise buildings to such severe ground motions is one of the most controversial subjects in the field of earthquake-resistant design in Japan. The criticality and uncertainty of the severe ground motions are investigated based on the theory of critical excitation in this project. The structural design methods for robust and resilient buildings are also studied.
