| Abstract: | The wind-induced vibration response of long-span lattice truss structure is analyzed here by using a frequency domain method based on random-vibration theory.To take a dry-coal shed as an example,ANSYS software is used for random vibration analysis.It is pointed out that the changes of vertical wind-induced displacement and the impact of the higher-order vibration mode are analyzed for the long-span lattice truss structure. |
