Investigation on the Earthquake Damage of the Goshō Suspension Bridge

Abstract

This investigation shows the earthquake damage of the Goshō Suspension Bridge, Fukui Prefecture. The general appearance of the failure is that the upper chords of the stiffening trusses buckled horizontally and the bridge deck flattened out during the earthquake, with the north span flattening out more than the south span. These damages were theoretically investigated and the results obtained explained the damages fairly well.
