Abstract
In order to deeply investigate the wind pressure characteristics and the windinduced vibration characteristics of cable-membrane structure, a monitoring study on the Expo Axis cable-membrane structure was carried out. The wind speed, wind pressure and wind-induced response were measured simultaneously. The wind pressure characteristics, the structure’s dynamic characteristics and the damping ratio were analyzed based on the monitoring data. The probability density distribution of wind pressure has some non-Gauss property. With the change of wind direction wind pressure coefficient by field measurement and wind tunnel test has the same trend. The acceleration RMS and power spectral density vary with the wind direction. The acceleration RMS increases with the increase of mean wind speed. Damping ratio decreases with the increase of natural frequency.
