Abstract

The invention provides a node assembly of a U-shaped steel-concrete composite beam and a rectangular steel tube concrete column, and relates to a node assembly of a steel tube concrete column. The node assembly of the U-shaped steel-concrete composite beam and the rectangular steel tube concrete column solves the problem that an existing node connection mode is unreasonable, the bearing capability of a node is too low, the ductility and energy-dissipating capacity of the core region of the node is insufficient, and therefore the node is damaged before other component. According to the node assembly of the U-shaped steel-concrete composite beam and the rectangular steel tube concrete column, a first rectangular steel tube, a second rectangular steel tube and a third rectangular steel tube are sequentially arranged from top to bottom, a node region inside partition plate is fixedly arranged between the second rectangular steel tube and the third rectangular steel tube, a node region reinforcing ring is fixedly arranged between the first rectangular steel tube and the second rectangular steel tube, four U-shaped steel beams are evenly distributed on four outer end faces of the second rectangular steel tube, a plurality of node region inserting plates are arranged on the node region reinforcing ring in the shape like a Chinese character 'jing', a steel bar is inserted in each node region inserting plate, and concrete is poured into the interior and the upper portion of each U-shaped steel beam. The node assembly of the U-shaped steel-concrete composite beam and the rectangular steel tube concrete column is used in constructional engineering.

Description

technical field [0001] The invention relates to a node assembly of a concrete-filled steel tube column, in particular to a node assembly of a U-shaped steel-concrete composite beam and a rectangular concrete-filled steel tube column, belonging to the technical field of building structures. Background technique [0002] U-shaped steel-concrete composite beam is a new type of composite member. U-shaped steel is used to replace the I-section steel in traditional composite beams, which can significantly improve the fire resistance, bending stiffness and overall stability of composite beams in the negative bending moment area of ​​the composite beam. Therefore, it has broad development prospects in practical engineering. At present, rectangular CFST columns have been widely used in practical projects. Compared with pure steel components, rectangular CFST columns can significantly reduce the amount of steel used, reduce the structural cost, and improve the fire resistance of steel...
