|Outline of Final Research Achievements
Due to 2011 Great East Japan Earthquake and 2016 Kumamoto Earthquake, many bridges suffered serious damages at structural boundaries and connections. In order to evaluate seismic response of bridges focused on discontinuity in structural system, shake table tests of seismic isolators in 2D were conducted to make rational numerical model, and improvement of design of collapse prevention device in bridge was proposed. And in order to evaluate seismic response of bridge focused on uncertainty, dynamic response of multi-degree-of-freedom systems was evaluated by changing the predominant frequency component of narrow band input for seismic action with high uncertainty by random vibration theory. Furthermore, new techniques were proposed to improve the post-peak behavior of reinforced concrete structure.
