弹性边界支承薄板在面内荷载下的屈曲

Buckling of Bearing Thin Plate With Elastic Edges by Plane Load

以工程设计中常见的 H型、T型断面构件为力学模型 ,对于面内单向均匀受压作用下板组结构中的薄板 ,研究了非加载边支承刚度的变化对屈曲荷载的影响规律。采用有限条模式进行了计算与分析 。

H shaped and T shaped sections,which are often used in actual steel work,are adopted as mechanics model by using the finite strip method to separate it,the law of influence from edgenon load supportin stiffness of uniform compression plate on its buckling load has been studied with altering stiffness of non load edge supporting,some results useful in actual project design are obtained.
