Description
Technical Field
The utility model belongs to the technical field of the building steel construction, in particular to assembled square steel tubular column-H shaped steel girder connected node.
Background
The node is most complicated in a structure in a stressed state because it bears axial force, bending moment and shearing force transmitted by columns above and below and beams at both ends. The node connecting part has enough bearing capacity, rigidity and ductility; the connection is complex in processing and installation and labor-consuming, so that the selection of a proper node structure is an important link in the design of a steel structure.
The north ridge earthquake in 1994, usa and the osaka earthquake in 1995, japan, indicate that a large amount of brittle fracture occurs in the conventional beam-column joint, the north ridge earthquake joint failure is characterized by crack extension from the root of the lower flange weld to the column section, and the osaka earthquake joint failure is characterized by crack development from the sector corner into the beam end. The main reasons found by the research are: (1) weld defects; because the flange and the web plate at the beam end are all welded, the bending resistance of the connection is basically equal to or slightly lower than the bending resistance of the whole section of the beam, and adverse factors such as certain defects of the welding seam, welding residual stress and the like are influenced, so that the brittle failure of the joint occurs before the frame beam enters plasticity; (2) the weld metal has low impact toughness; large tests performed after the northern ridge earthquake have high requirements on the weld quality, and the large tests are all connected by using E70T-4 type low-toughness bars, so that early damage still occurs to the connection.
H-shaped steel column-H-shaped steel beam connection nodes are used in large quantity at home and abroad, but the connection of the steel tube column and the H-shaped steel beam at the other side is relatively lack of use; the rigidity of the H-shaped steel column in the two main shaft directions is greatly different, and the H-shaped steel column is obviously concave in shape, so that the indoor space decoration is inconvenient. Compared with an H-shaped steel column, the square steel column has no weak shaft, and has the advantages of strong bearing capacity, high torsional rigidity, steel saving, convenience in site construction and the like. The existing connection form of the square steel pipe column and the H-shaped steel beam is mostly welded, the components are not easy to transport and convenient to construct, meanwhile, the building appearance design and the indoor decoration are inconvenient, and the welding quality on site is difficult to guarantee.
The conventional square steel pipe column and H-shaped steel beam joint are welded, but the weld joint connection is easy to break and the weld quality is easily influenced by construction conditions, and common bolts are not convenient to install when the closed structure of the square steel pipe column is used, so that the split bolt connection joint capable of reducing the field welding workload is increasingly concerned by people. However, when the split bolt is used, a large bolt pretightening force is generated, so that the column wall has obvious concave deformation, and at present, two processing methods are commonly used for improving the rigidity of the node domain: firstly, concrete is poured into the square steel pipe column; and secondly, a sleeve or a steel plate is added on the wall of the square steel pipe column. The former needs to pour concrete on site, reduces the construction efficiency and cannot realize green construction; meanwhile, the concrete can not be quickly constructed due to the time required for solidification; the latter has a limited degree of improvement in the stiffness of the node region, and the column wall is also somewhat concave.
The existing nodes have poor form performance, low rigidity, insufficient bearing capacity and ductility, difficult installation and unfavorable node seismic resistance due to the fact that plasticity develops on beam ends and columns.
