蜂窝式轴压构件腹板局部稳定问题研究

Research on partial stabilization of sternum of honeycomb pull-down component

运用有限元分析软件ANSYS得出实腹式构件在轴心压力作用下的腹板弹性屈曲系数,验证有限元模型建立的准确性。然后运用ANSYS软件计算蜂窝式构件在轴力作用下腹板弹性屈曲系数,研究其随参数变化的趋势。

It obtains elastic-flexion coefficient of sternum of solid-web component under axis stress applying for finite element software ANASYS and proves accuracy of establishment of finite element model, and calculates elastic flexion coefficient of sternum of honeycomb pull-down component under axis stress applying for ANASYS and researches its trend with variation of parameter.
