摘要
对多高层钢结构中钢板剪力墙的极限抗剪承载力进行了计算和分析 ,给出了钢板剪力墙剪切屈曲剪力、受剪屈曲后拉力场所承担剪力以及考虑框架杆件作用的极限剪力计算公式。利用文中所给公式对不同尺寸的剪力墙进行了计算 ,计算表明 ,对于宽厚比较大的钢板 ,屈曲后拉力场承担的剪力远远大于屈曲剪力 。
The ultimate shear capacity of steel plate shear wall in multi-story steel structures is calculated and analyzed in this paper.It is presented that the calculation equations of steel plate shear wall′s buckling shear,post-buckling shear provided by tension field and ultimate shear which considering the contribution of frames.Steel plate shear walls with different dimensions are calculated.The results show that for the steel plates with large width-thickness ratio post-buckling shear is much greater than buckling shear.The design of steel plate shear wall considering the post-buckling strength is more reasonable and economical.
