Advancing and reviewing of research on aerodynamic admittance of bridges

Abstract

Abstract: 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.

Key words: buffeting of bridge, aerodynamic admittance, method of cross power spectrum
