The Influence of the Strong Aftershocks on Seismic Performance on Long-Span Arch Bridges Based on the Energy Method

Abstract:

Equivalent seismic wave can be formed by a main wave and two strong aftershock waves on the basis of energy equivalent principle. With a long-span arch bridge as a research object, the hysteretic energy distribution of the pier and arch were got by the action of the main wave and equivalent seismic wave based on energy method. And then the situation of bridge damage was assessed by Seismic Ditao Niu damage index, the regular pattern of structure damage affected by strong aftershock was revealed as well.
