摘要
基于随机振动理论,采用频域分析方法对大跨度网架风振响应进行分析,以某电厂大跨干煤棚为例,用有限元ANSYS软件对其进行随机振动分析,分析了大跨网架的竖向风振位移的变化情况,及高阶振型对其的影响情况。
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.
