| Abstract: | Aimed at the wind-induced vibration of the long-span grid roof,based on FEM and the data obtained form the wind load simulation method through the linear filters to sequences of random numbers,the analysis of time-history is used to calculate the wind-induced vibration factor of vertical displacement and the wind-induced vibration factor of inner-force of beam string structure.Furthermore,the changing law of wind-induced vibration factors of the displacement and the inner-force of beam string structure are ... |
