Abstract:
The relevant research progress of seismic resilient girder bridges presented on the 16th and 17th World Conference on Earthquake Engineering (WCEE) was sorted and summarized. Specifically, the latest research progress of post-tensioned prestressed rocking self-centering girder bridges and other novel seismic resilient girder bridge systems was analyzed. The research on the application of high-performance materials in resilient girder bridges was summarized, and the engineering application of self-centering girder bridges at home and abroad was outlined. The research on the replaceable devices, such as self-centering energy dissipation devices and displacement-limiting devices, in seismic resilient girder bridge structures was presented. The seismic performance of girder bridge structures with additional replaceable devices was discussed. The evaluation methods for the seismic resilience of a single girder bridge and that of a bridge network were reviewed. The research orientation and development trend of seismic resilient girder bridge structures were explored. Research results show that, the post-tensioned prestressed self-centering girder bridges with additional replaceable energy dissipation devices are the most widely studied seismic resilient girder bridge structures, and a number of demonstration projects have been completed. The performance of this type of structure in strong earthquakes remains to be verified by actual earthquakes. In terms of replaceable devices, new structures and new configurations of replaceable devices should be developed by availing high-performance materials. On this basis, reasonable technologies for connecting such devices with bridges and seismic design methods can be investigated. In addition, the completed girder bridges in China are faced with outstanding issues in developing seismic resilience evaluation methods, capacity enhancement technologies, and design theories for existing girder bridge structures under consideration of the influences of multiple factors, such as performance degradation and demand increase. © 2022 Chang'an University.
