【摘要】：首先对双钢板混凝土组合剪力墙中的钢板进行了屈曲理论分析,对核心受约束混凝土进行了受力分析.以北京中国尊核心筒结构底部剪力墙为原型,进行了1/4缩尺模型的双钢板混凝土组合剪力墙试件和内置钢板混凝土组合剪力墙的轴压性能试验,对比分析其荷载-位移曲线、轴压承载力等.考虑到钢板屈曲对钢板轴压承载力的影响以及受约束混凝土轴心抗压强度的提高,提出了双钢板混凝土组合剪力墙轴压承载力的计算公式,与应用其他计算方法计算得到的试验试件的轴压承载力相比,本文提出的计算公式的计算结果与试验结果吻合度最高.结合其他文献中双钢板混凝土组合剪力墙轴压性能试验的相关数据进行验证,表明利用本论文提出的计算公式得到的轴压承载力计算值与试验结果吻合较好.
[Abstract]:First, the buckling theory of the steel plate in the double-plate concrete composite shear wall is analyzed, and the stress of the core confined concrete is analyzed. Taking the shear wall at the bottom of the core tube structure in Beijing as the prototype, the axial compression behavior tests of double steel plate concrete composite shear wall and built-in steel plate concrete composite shear wall were carried out with a 1 / 4 scale model, and the load-displacement curves were compared and analyzed. Axial bearing capacity, etc. Considering the influence of buckling of steel plate on the bearing capacity of steel plate and the improvement of axial compressive strength of confined concrete, a formula for calculating axial compression capacity of double-plate concrete composite shear wall is proposed. Compared with the axial compression capacity calculated by other calculation methods, the calculated results obtained in this paper are in the best agreement with the experimental results. The results of axial compression test of double-plate concrete composite shear wall in other literatures show that the calculated values of axial compression capacity obtained by this paper are in good agreement with the experimental results.
