The invention discloses a double-layer circular steel tube concrete hollow column with a negative Poisson's ratio effect and a design method. The double-layer circular steel tube concrete hollow column comprises an outer-layer circular steel tube with the negative Poisson's ratio effect, core concrete and an inner-layer common circular steel tube, wherein the outer-layer circular steel tube with the negative Poisson's ratio effect is of a hole structure with periodic transverse and vertical alternation; the relation between the outer diameter D of the outer-layer circular steel tube with the negative Poisson's ratio effect and the height L of the circular steel tube concrete hollow column meets the condition that L/D is more than 2.5 and less than 10; the relation between the thickness t1 of the outer-layer circular steel tube with the negative Poisson's ratio effect and the outer diameter D meets the condition that D/t1 is more than 30 and less than 40; and the relation between the thickness t2 of the inner-layer common circular steel tube and the outer diameter D of the outer-layer circular steel tube with the negative Poisson's ratio effect meets the condition that D/t2 is more than 45 and less than 55. The circular steel tube concrete hollow column disclosed by the invention has the advantages of high bearing capacity, good ductility, difficulty in bulging and deformation and the like.
本发明公开了具有负泊松比效应的双层圆钢管混凝土空心柱及设计方法，包括具有负泊松比效应的外层圆钢管、核心混凝土和内层普通圆钢管，所述具有负泊松比效应的外层圆钢管为具有周期性横竖交替的孔洞结构；所述具有负泊松比效应的外层圆钢管的外直径D与圆钢管混凝土空心柱的高度L的关系应满足2.5<10；所述具有负泊松比效应的外层圆钢管的厚度t1与之外直径D的关系应满足30<40；所述内层普通圆钢管的厚度t2与具有负泊松比效应的外层圆钢管的外直径D的关系应满足45<55。本发明圆钢管混凝土空心柱具有承载力高、延性好、不易鼓曲变形等优点。
