The effects of different wind speed and different direction to the roof surface pressure coefficient and the roof wind load are studied. Based on the wind tunnel test results, the wind vibration response analysis of the roof structure is conducted. The wind pressure factor and the wind vibration factor is provided, which can be referenced for the related design..Keywords:Large span space structure, wind tunnel test, wind pressure factor,wind vibration factor
