State-of-the-art review of bridge wind engineering in 2019

Bridge wind-engineering is an interdisciplinary that aims to study the aeroelastic stability of long-span bridges, as well as wind-induced vibrations and corresponding countermeasures, and provides theoretical basis, methods and techniques for wind-resistant design of bridges. In recent years, the boom of long-span and super long-span bridges advances the development of bridge wind-engineering, giving rise to a series of achievement in both theoretical,test method and wind vibration control technolagy. Focusing on the main problems in the wind-resistant design of long-span bridges, this paper introduces and reviews the main research progress of bridge wind engineering in field measurement of bridge potential wind characteristics, nonlinear flutter characteristics and calculation theory of long-span bridges, chattering calculation theory of bridges, calculation theory of bridge vortex induced vibration and control technology since 2019.
