摘要
当前,我国钢管混凝土(concrete filled steel tube,CFST)拱桥建设发展迅速,大量CFST拱桥建成于强震频发区,其抗震安全问题受到广泛关注。为了全面掌握国内外在CFST拱桥抗震领域的研究进展状况,首先,调研了国内外360篇与CFST拱桥抗震相关的研究文献,从发文量就其研究方向与研究趋势进行了宏观论述;然后,从CFST拱桥抗震模拟与分析方法、结构响应特性、震致损伤分析、减隔震等四个方面详细总结分析了当前的研究进展和不足;最后,对CFST拱桥抗震研究值得进一步探讨的方向进行了展望。研究表明,准确获取结构地震响应的动力分析方法、构件间动力响应的耦合行为、结构设计参数优化和合理设计方法、减隔震措施的合理布设方法及其结构响应的影响机理、普适性的损伤评估流程等是CFST拱桥抗震研究中具有重要意义的热点和方向;抗震风险评估、数字化技术的融合、普适性的研究手段与数据分析方法是今后值得重点研究的内容。本研究进展总结可为已建和待建CFST拱桥在抗震分析、设计及评估等方面提供参考。
Currently,the construction of concrete filled steel tube(CFST)arch bridges in China is developing rapidly,and a large number of CFST arch bridges are located in the high-seismicity zones.The seismic resistance issues of CFST arch bridges have received widespread attention.This article first surveyed 360 domestic and foreign research literatures related to the seismic resistance of CFST arch bridges,and provided a macro discussion on their research direction and trends based on the number of publications.Afterwards,the current research progress and shortcomings were summarized in detail from four aspects:seismic simulation and analysis methods,seismic response characteristics,seismic damage analysis,and seismic isolation of CFST arch bridges.Finally,an outlook was made on the issues worth further research on the seismic resistance of CFST arch bridges in the future.The results show that the dynamic analysis method can accurately obtain the seismic response of structures,the coupling behavior of dynamic response amongst components,the optimization and reasonable design method of structural design parameters,the reasonable deployment method of seismic reduction and isolation measures and the mechanism of their impact on structural response,as well as the universal damage assessment process are of great significance for the seismic resistance of CFST arch bridges.In addition,seismic risk assessment,the application of digital technology,and universal research methods and data analysis methods are key areas worth studying in the future.The research can provide a reference for the engineering and academic communities in the seismic analysis,design,and evaluation of existing and pending CFST arch bridges.
