| Abstract: | The amount of work of the wind vibration and wind load of large roof structures is very large. Considering the compositive effect of horizontal wind and vertical wind, this paper analyzed the wind vibration of large roof structures with the frequency domain method, and developed the wind load analyzing software which can connect with the finite el- ement software and combine several modes. The effectiveness and precision of the method and software is verified by the analysis of the wind response of the roof of a stadium. |

| Keywords: | wind vibration coefficient vertical wind frequency domain analysis modes composition |
