摘要

摘要: 梳理和总结了第16、17届世界地震工程大会(WCEE)中关于韧性抗震梁桥相关的研究进展；分析了后张预应力摇摆自复位梁桥与其他新型韧性抗震梁桥体系的最新研究进展，总结了高性能材料在韧性梁桥中的应用研究，并介绍了国内外自复位梁桥的工程实践；介绍了自复位耗能装置和限位装置等韧性抗震梁桥结构中的可更换装置研究，讨论了附加可更换装置的梁桥结构抗震性能；总结了单体梁桥和桥梁网络的抗震韧性评估方法，探讨了韧性抗震梁桥结构的研究方向和发展趋势。研究结果表明：附加可更换耗能装置的后张预应力自复位梁桥是研究最为广泛的韧性抗震梁桥结构，且已建成了多座示范工程，该类结构在强震中的表现有待实际地震验证；需要结合高性能材料开发可更换装置新结构与新构造，在此基础上研究其与桥梁的合理连接技术及抗震设计方法；考虑性能退化、需求增加等多因素影响的既有梁桥结构抗震韧性评价方法和能力提升技术及其设计理论，是中国已建梁桥面临的突出问题。

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.
