| 摘 要： | 采用有限元软件ANSYS 15.0对多组外加盖板斜加劲薄钢板墙(CSW)模型进行弹性屈曲分析,研究盖板相似比、盖板高厚比、加劲肋高厚比及肋板刚度比等因素对CSW模型屈曲性能的影响,探讨提高CSW结构屈曲应力的方法,最终给出了CSW肋板刚度比的门槛刚度以及盖板高厚比的合理取值范围。

| Abstract: | Elastic buckling analysis of several series of vertical Cover Plate Stiffening Thin Plate Shear Wall(CSW)models was carried out under shear loading by the finite element software ANSYS 15.0.The effects of the ratio of cover plate similarity,height-to-thickness ratio of cover plate,height-to-thickness ratio of stiffener and ribbed plate stiffness ratio on shear buckling behavior of the CSW were investigated.The methods of improving the critical shear buckling stress were also discussed.Then the threshold stiffness of stiffness ratio of CSW ribbed plate and the reasonable range of height-to-thickness ratio of cover plate was proposed. |
