摘要:
分析了竖向加劲薄钢板剪力墙的受力和变形,提出了考虑加劲肋贡献的竖向加劲薄钢板剪力墙的抗侧刚度,以及考虑屈曲后强度的竖向加劲薄钢板剪力墙的抗侧承载力计算公式.构建梁柱铰接足尺模型进行有限元分析.公式计算结果与有限元结果对比表明:抗侧刚度及抗侧承载力计算值与有限元结果吻合较好; 竖向加劲肋的设置提高了薄钢板剪力墙的弹性屈曲应力,考虑屈曲后强度的竖向加劲薄钢板剪力墙的抗侧承载力应包含弹性屈曲荷载和屈曲后强度的贡献.竖向荷载会降低竖向加劲薄钢板剪力墙的抗侧刚度和抗侧承载力,增大加劲肋数量可显著减小竖向荷载对竖向加劲薄钢板剪力墙抗侧刚度的影响,增大加劲肋截面积对其影响较小.
Abstract:
In this paper, the mechanical behaviour and deformation of the thin steel plate shear wall with vertical stiffeners(SPSW-VS)were studied. The formulas of lateral stiffness with the contribution of stiffeners and lateral-resistant capacity of thin SPSW-VS considering post-buckling strength were obtained. Then the finite element analysis of full-scale models with pinned boundary connections was conducted, followed by comparison works. It is indicated that the predicted lateral stiffness and lateral-resistant capacity consisting buckling strength and post-buckling strength agree well with the numerical analysis results. An introduction of vertical stiffeners would increase the elastic buckling stress of the thin SPSW-VS. Moreover, vertical load would decrease the lateral stiffness and lateral-resistant capacity of the thin SPSW-VS, but this effect would be reduced significantly when increasing the number of stiffeners rather than the area of the stiffeners.
