Round steel pipe concrete with negative Poisson's ratio effect and design method thereof
The invention discloses round steel pipe concrete with a negative Poisson ratio effect and a design method of the round steel pipe concrete. The round steel pipe concrete comprises a round steel pipewith a negative Poisson ratio effect, a steel support with a negative Poisson ratio effect and concrete. The steel support is arranged on the inner wall of the round steel pipe. Concrete is filled inthe round steel pipe. The round steel pipe and the steel support are of hole structures which are alternately and periodically arranged in horizontal and vertical directions. The relationship betweenthe height L of the round steel pipe and the diameter D of the round steel pipe should comply with 2.5<5, the relationship between the thickness r of the round steel pipe and the diameter D of theround steel pipe should comply with 30<40, the height of the steel support is equal to L, and the width d of the steel support should comply with 0.6<0.7. The round steel pipe concrete can actively restrain the transverse deformation of core concrete, thereby improving the compressive bearing capacity and ductility of the structure. Meanwhile, the hole design of the negative Poisson ratiosteel pipe can improve the anti-seismic performance of the structure.
本发明公开了一种具有负泊松比效应的圆钢管混凝土及其设计方法，包括具有负泊松比效应的圆钢管、具有负泊松比效应的钢支撑和混凝土；所述钢支撑设置在圆钢管的内壁，所述混凝土填充在圆钢管的内部；所述圆钢管和钢支撑为具有周期性横竖交替的孔洞结构；所述圆钢管的高度L与圆钢管的直径D关系应满足：2.5<5；所述圆钢管的厚度r与圆钢管的直径D关系应满足30<40；所述钢支撑的高度等于L，钢支撑的宽度d应满足：0.6<0.7。本发明圆钢管混凝土能够主动约束核心混凝土的横向变形，提高了结构的受压承载力和延性。同时负泊松比钢管的孔洞设计能够提高结构的抗震性能。
