With the construction of super-long span bridges, such as the Canakkale 1915 Bridge in Turkey, the Zhanggao River-crossing Corridor and the Xihoumen Highway-Railway Bridge in China, the wind engineering research of bridges is facing new challenges. Following the research progress of the previous year, this paper focuses on the key problems of bridge wind engineering, including bridge flutter, vortex-induced vibration and buffeting. Through sorting out the literatures of main academic journals in the field of wind engineering, the state-of-the-art focusing on the main aspects of wind-resistant of long-span bridges in 2020 was reviewed and discussed.
