桥梁结构气动导纳研究回顾及其新进展

Advancing and reviewing of research on aerodynamic admittance of bridges

气动导纳函数是桥梁抖振分析中的重要气动参数,国内在这方面的研究几乎处于空白阶段.在分析文献资料的基础上,系统地介绍了气动导纳函数的来源、历史研究及经验公式等.并对作者在气动导纳研究方面的最新成果和进一步需要进行的工作进行了简单介绍,从而为今后的研究工作提供了参考.

Aerodynamic admittance was an important aerodynamic factor in analysis of buffeting of bridges.It was nearly no research in China.Based on the summarization of reports of research on aerodynamic admittance,source,research history and formula of aerodynamic admittance were systemically introduced.Meanwhile,new achievements and more work about aerodynamic admittance research are introduced,which have very important significance for reference to further research.
