Connecting structure of steel-encased-ECC composite beam and concrete filled steel tubular column
The invention belongs to the technical field of building structures, and particularly relates to a steel-encased-ECC composite beam and concrete-filled steel tube column connecting structure which comprises a concrete-filled steel tube column, steel encased and an ECC composite beam, the concrete-filled steel tube column comprises a steel tube, concrete filled in the steel tube, and an upper ring plate and a lower ring plate arranged in the steel tube; the outer wrapping steel comprises an outer wrapping box type section and an outer wrapping U-shaped section, and one end of the outer wrapping box type section is welded to the steel pipe concrete column; the ECC composite beam comprises a common concrete beam section, an ECC beam section and a reinforcement cage, the reinforcement cage is arranged in the common concrete beam and the ECC beam in a penetrating mode, the outer side of the ECC composite beam is wrapped with the encased steel, and the reinforcement cage is welded to the inner side of the encased steel; the outer wrapping section adopts outer wrapping steel to replace stirrups and adopts ECC to replace common concrete; the problems that steel bars of the concrete-filled steel tubular column and the reinforced concrete beam are difficult to bind, the construction technology is complex, the concrete pouring quality is poor, and the joint ductility is poor are solved, and the advantages of high ductility, high toughness and the like are achieved.
本发明属于建筑结构技术领域，具体涉及一种外包钢‑ECC组合梁与钢管混凝土柱连接结构，包括钢管混凝土柱、外包钢和ECC组合梁，钢管混凝土柱包括钢管、填充于钢管内的混凝土、设置于钢管内的上环板、下环板；外包钢包括外包箱型段和外包U型段，外包箱型段一端与钢管混凝土柱焊接；ECC组合梁包括普通混凝土梁段、ECC梁段和钢筋笼，钢筋笼穿设在普通混凝土梁和ECC梁内，外包钢包裹在ECC组合梁外侧，钢筋笼与外包钢内侧焊接；外包段采用外包钢代替箍筋，ECC代替普通混凝土；解决了钢管混凝土柱与钢筋混凝土梁钢筋绑扎困难、施工工艺复杂、混凝土浇筑质量差、节点延性差等问题，具有高延性、高韧性等优点。
