摘要：针对高层和超高层框架混凝土柱构件，设计了一种新型的矩形八角组合螺旋箍筋柱。与传统成型钢筋柱相比，矩形八角组合螺旋箍筋柱具有多项优势。以传统矩形八角组合箍筋柱的柱构件作为对照，通过非线性有限元分析模拟了柱的低周反复荷载试验，研究了不同轴压比下柱水平承载性能，得到了不同工况下的极限承载力、荷载-位移曲线和破坏形态。结果表明：有限元分析结果与试验结果吻合较好；随着轴压比的提高，柱的水平承载力变大，荷载-位移曲线的强度下降段变陡，延性变差；成型矩形八角组合螺旋箍筋柱与传统矩形八角组合箍筋柱的刚度、承载力和延性接近。综上所述，成型矩形八角组合螺旋箍筋柱在构造和受力性能上均具有良好的适用性，在建筑结构尤其是高层和超高层结构中具有推广价值。

Abstract: For high-rise and super high-rise frame concrete column components, a new type of rectangular-octagonal composite spiral stirrups column is designed. Compared with traditional formed steel bars column, the rectangular-octagonal composite spiral stirrups column has many advantages. Taking the column member of the traditional rectangular octagonal combined stirrup column as comparison, the low cycle reversed load test of the column was simulated through nonlinear finite element analysis, and the horizontal load-bearing performance of the column under different axial compression ratios was studied. Ultimate bearing capacity, load-displacement curve and failure mode under different working conditions were obtained. The results show that the finite element analysis results are in good agreement with the experimental results. With the increase of the axial compression ratio, the horizontal bearing capacity of the column becomes larger, the strength drop of the load-displacement curve becomes steeper, and the ductility becomes worse. From the perspective of stiffness, bearing capacity and ductility, the performance of the columns with fabricated rectangular-octagonal composite spiral stirrups is close to that of the columns with traditional form of stirrups. To sum up, the fabricated rectangular-octagonal composite spiral stirrups column has good applicability in structure and mechanical performance, and has promotion value in building structures, especially high-rise and super high-rise structures.

Keywords: high-rise frame; fabricated steel bar; rectangular-octagonal composite; spiral stirrups column; horizontal load-bearing performance; stiffness; ductility
