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 joint assembly of a steel pipe concrete column, in particular to a joint assembly of a U-shaped steel-concrete composite beam and a rectangular steel pipe concrete column, and belongs to the technical field of building structures. Background technique [0002] U-shaped steel-concrete composite beam is a new type of composite member. Using U-shaped steel instead of I-shaped section steel in traditional composite beams can significantly improve the fire resistance, bending stiffness and overall stability of composite beams in the negative moment zone. Therefore, it has broad development prospects in practical engineering. At present, rectangular concrete-filled steel tube columns have been widely used in practical engineering. Compared with pure steel components, rectangular concrete-filled steel tube columns can significantly reduce the amount of steel used, reduce structural costs, and improve the fire resistance of steel com...
