摘要
钢板剪力墙的初始侧向刚度是分析其力学性能的基础。提出了VV-SPSW初始侧向刚度的计算公式,并对126个VV-SPSW进行了有限元静力推覆分析,得到其初始侧向刚度的数值模拟值。将两者结果比较表明,所提计算公式具有良好的精度。进而探讨了剪应力不均匀系数、加劲肋端部约束弯矩影响系数、钢板厚度与高宽比、加劲肋截面积与根数等对VV-SPSW初始侧向刚度的影响,对3种增加VV-SPSW初始刚度的方法进行经济性比较,并给出了基于初始侧向刚度的VV-SPSW若干构造措施的合理建议。
A steel plate shear wall＇s initial lateral stiffness is the basis for analysing its mechanical behaviors. This paper proposed the formulas of VV-SPSW initial lateral stiffness,and FEM pushover analysis of 126 VV-SPSW models was conducted,also its initial lateral stiffness numerical values were got. The comparison between the said results showed that the proposed formulas had good accuracy. Then it was discussed the effects of shear stress non-uniform distribution coefficients,the plate thickness and height-width ratio,stiffeners cross-sectional area and numbers on VV-SPSW initial lateral stiffness,it was compared the economy of three methods of increasing VV-SPSW initial stiffness. And it was given that the reasonable suggestions of several structural measures for VV-SPSW based on the initial lateral stiffness.
