Abstract

 As the lessons from severe damage of civil infrastructures due to Tsunami and ground motion in the 2011 Great East Japan Earthquake, “Anti-Catastrophe” concept can be a paradigm shift in structural / seismic design method. In a conventional design, seismic safety of a structural system is verified against “design” ground motion. But “Anti-Catastrophe” concept requests for structural designers to concern the possibility of catastrophic event caused by severe action unestimated in the design method. JRA Design Specifications for Highway Bridges was revised in 2012 and a principle similar to “Anti-Catastrophe” concept was adopted. In this paper, “Anti-Catastrophe” concept in the specifications is summirised and challenges are considered to produce effective measure in seismic design method based on the review of recent domestic and foreign trend of structural design.
