摘要
空腹夹层板由空腹梁交叉组成。以简支条件为例,推导了空腹梁的折算剪切刚度,讨论了剪切变形对空腹梁的变形影响,分析表明,空腹梁的变形主要由整体弯曲内力引起,因此空腹夹层板可以在考虑剪切变形的基础上简化为密肋板进行刚度分析。还推导了两种空腹夹层板简化分析的等代刚度。并讨论了空腹夹层板的若干静力性能。
The vierendeel sandwich plate is composed of cross vierendeel girder.This paper educed the conversion shear rigidity of vierendeel girder with simply supported ends,and disucssed the influence of shear deformation on the flexibility of vierendeel girder.The analysis proved that the deformation is mostly produced by whole bend internal force,so a simplified stiffness analysis method can be made on the vierendeel sandwich plate as on the multiribbed plate.Further,it educed two kinds of predigest bending stiffness of the vierendeel sandwich plate,and also investigated the static behavior of this structure.
