This paper is the second of a two-part study on the seismic vulnerability of deck bridges supported on steel pile bents. A conceptual elastic cap/elasto-plastic steel pile retrofit strategy is proposed in this part with the aim of strengthening the connection and ensuring plastification takes place only in the steel pile. An experimental program was carried out to assess the retrofit strategy. On the basis of the experimental results for existing as well as retrofitted connections, a seismic vulnerability analysis for bridges supported by steel pile bents was performed. Fragility curves for such structures were developed using a simplified fundamental mechanics-based approach. The study showed that the retrofitted connections exhibited superior energy absorptions with respect to the existing connections. Fragility curves also demonstrated the effectiveness of the retrofit strategy proposed.

Seismic Vulnerability Analysis

Dam damaged is one of common forms about lifeline engineering after earthquake raids. Based on the analysis of the seismic damaged conditions of 825 dams in Mianyang City, this paper establishes a dam’s seismic vulnerability matrix that suite for the Chinese specification. Compares the Mianyang city’s earth-rock dam seismic vulnerability matrix with the ATC-13’s that based on Delphi method, the vulnerability of dams in the Wenchuan earthquake is quite different with ATC-13’s, earth-rock dams of Mianyang City appear to be more vulnerable during earthquake. Base on date of seismic vulnerability matrix in Mianyang city, vulnerability curves are established. The vulnerability curves that fitted by beta function can be used to predict Chinese earth-rock dam’ seismic damage.
