Steel pipe with gradient change and negative Poisson's ratio characteristics and steel pipe concrete column
The invention discloses a steel pipe with gradient change and negative Poisson's ratio characteristics and a steel pipe concrete column, and belongs to the technical field of constructional engineering. A plurality of Karisenib oval line holes are distributed in the steel pipe with the negative Poisson's ratio characteristic, under a two-dimensional Cartesian coordinate system, the expression of the Karisenib oval line is (x2 + y2) 2 + (s2-d2) (y2-x2)-s2d2 = 0, in the formula, s is half of the long axis of the Karisenib oval line, and d is half of the short axis of the Karisenib oval line. The steel pipe has the negative Poisson's ratio characteristic, the shape control parameters and the pore distance change mode of the Karisi oval line can be adjusted according to the axial compression resistance index, so that the gradient distribution form of the pores is changed, the axial deformation requirement is met, complex structural design and installation procedures are not needed, the manufacturing and installation cost is reduced, and the production efficiency is improved. And different application requirements are met. After concrete is filled, the steel pipe concrete column is obtained, radial expansion of the inner concrete column is restrained through the radial shrinkage deformation effect of the steel pipe when the steel pipe is pressed in the axial direction, and the compression resistance is enhanced.
本发明公开了一种具有梯度变化和负泊松比特性的钢管及钢管混凝土柱，属于建筑工程技术领域。所述具有负泊松比特性的钢管上布有若干卡西尼卵形线孔，在二维笛卡尔坐标系下，所述卡西尼卵形线的表达式为：(x2+y2)2+(s2‑d2)(y2‑x2)‑s2d2＝0，式中，s为卡西尼卵形线长轴的一半，d为卡西尼卵形线短轴的一半。本发明的钢管具有负泊松比特性，可以根据轴向抗压性能指标，调整卡西尼卵形线的形状控制参数与孔隙距离变化模式，从而改变孔的梯度分布形式，满足轴向变形需求，无需复杂的结构设计和安装工序，降低制造和安装成本，适应不同的应用需求。填充混凝土后，获得钢管混凝土柱，利用钢管在轴向受压时的径向收缩变形效应，抑制内部混凝土柱的径向膨胀，增强抗压性能。
