Research summary
Seismic Performance Evaluation of Highway Bridges As Japan is a highly seismic country, earthquake resistant design technique for infrastructures has progressed. Our laboratory promotes research aimed at protecting people, communities and their culture against earthquakes and other natural disasters. Please note that our main target structures are bridges, and we don't investigate issues in buildings. Bridges are one of the most important infrastructures. Destruction of bridges can significantly compromise logistic operations, not only having a major impact on daily living activities but also delaying reconstruction of suffered area. We conduct experiments and numerical analyses to construct safe and robust bridges against earthquakes, tsunamis and floods to save invaluable human lives. _

Message
1.	Earthquake disaster reduction of infrastructures Earthquake engineering is one of the major fields of civil engineering, which protects human lives and cities from natural disasters. [Earthquake resistant design of bridges] Many bridges were collapsed due to past earthquake disasters. If a bridge suffers damage due to earthquakes, loss of links in the lifeline networks affects on the restoration process of cities. Numerical simulations are carried out for isolated bridges as well as bridges with dampers. [Tsunami impacts on bridges] Many bridges were lost due to 2011 East Japan earthquake and tsunami. Safe bridges need to be constructed and maintained for not only earthquake vibration but also tsunami wave. Experiments and numerical simulations are carried out to design safer bridges for tsunami.
