SEISMIC RETROFIT DESIGN OF LARGE CABLE-SUPPORTED BRIDGES IN TOKYO
This paper describes the seismic retrofit of 3 cable-supported bridges in Tokyo: the Rainbow Bridge, the Yokohama Bay Bridge, and the Tsurumi Fairway Bridge. Site-dependent far-field ground motion due to possible maximum credible earthquake is calculated using a fault rupture model together with wave propagation techniques. The nonlinear seismic response of the bridges, including soil-structure interaction, is computed and it is found that all 3 bridges may suffer considerable damage. For the structural elements that receive severe damage, careful retrofit design is conducted. Taking into account that large bridges are complex structural systems, increase of the structural redundancy and fail-safe concept is emphasized in the retrofit design.
