Compound steel pipe concrete column with built-in energy dissipation assembly
The compound concrete-filled steel tube column comprises a square steel tube column and a cylindrical opposite-pull energy dissipation assembly arranged in the bottom of the square steel tube column, and the cylindrical opposite-pull energy dissipation assembly comprises a steel bar shell, a center column and an elastic supporting assembly connected between the steel bar shell and the center column. The steel bar shell and the elastic supporting assembly are of an opposite-pulling structure, the elastic supporting assembly restrains deformation of the steel bar shell through deformation energy consumption of the elastic supporting assembly, the steel bar shell and the square steel pipe column are connected through a fastener, the rigidity of the bottom of the square steel pipe column is improved, yield deformation of the bottom of the steel pipe column is kept to a certain degree, and buckling damage is avoided. And meanwhile, the cylindrical opposite-pulling energy dissipation assembly can limit inward or outward yielding of the steel pipe, and various possible stress forms of the square steel pipe column under the earthquake action can be effectively coped with. In addition, the cylindrical opposite-pulling energy dissipation assembly can reset through opposite pulling after an earthquake, so that the steel pipe column is reset.
本发明公开了一种内置耗能组件的复式钢管混凝土柱，包括方形钢管柱和其底部内置的圆柱状对拉耗能组件，圆柱状对拉耗能组件包括钢条外壳、中心柱及钢条外壳与中心柱之间连接的弹性支撑组件。即钢条外壳与弹性支撑组件之间为对拉结构，弹性支撑组件通过其自身的变形耗能来约束钢条外壳的变形，钢条外壳与方形钢管柱通过紧固件连接，提高方形钢管柱的底部刚度，使钢管柱底部的屈服变形维持在一定程度，避免屈曲破坏。同时圆柱状对拉耗能组件可限制钢管向内或向外屈服，可以有效应对在地震作用下方形钢管柱各种可能的受力形式。另外，圆柱状对拉耗能组件可在震后通过对拉自复位，使钢管柱复位。
