Abstract: In this study, we developed a data processing program for the wind on bridge based on C# programming language, Windows Presentation Foundation (WPF) framework and the idea and process used in analyzing and processing wind data. The program proposed functioned in data segmentation, processing of bad points and calculating of wind speed, wind direction, turbulence intensity, gust factor, integral scale and power spectral density. Moreover, it realized the rapid and automatic calculation of the wind characteristic parameters and convenient processing of the massive wind data observed.
