| Abstract: | A great deal of work is necessary to calculate the coefficient of the wind vibration.Considering the compositive effect of horizontal wind and vertical wind,the wind vibration characteristics of large roof structures are analyzed by the frequency domain method,and the wind load analyzing software,which can connect with the finite element software and combine several modes is developed.The effectiveness and precision of the method and software are verified by the analysis of the wind response of a stadium's roof. |

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