The steel-concrete combined structure is a structural form which is formed by combining section steel or steel pipes and concrete and then working together. The application of the steel-concrete composite structure starts in 1897, and John Lally in the United states initiates filling of concrete in a circular steel pipe to serve as a bearing column of a house; in the 50 s of the 20 th century, the concept of "stiff reinforced concrete" was proposed in textbooks on reinforced concrete structures by scientists and engineers in the former soviet union. In the 80 s of the 20 th century, steel-concrete composite structures were developed rapidly when both reinforced concrete structures and ordinary steel structures could not meet the actual engineering needs.
The more outstanding problems encountered in the current engineering design are:
(1) the axial force of the column is increasingly greater; (2) the requirement of the earthquake-resistant design on the ductility level of a structure or a member is improved; (3) the ability of structures to resist contingencies needs to be improved; (4) the durability of the structure is required to be improved.
Aiming at the four problems, the problems that a reinforced concrete structure and a steel structure are not suitable in the design of high-rise, super high-rise, large column net and large span structures exist. One of the effective solutions to these problems is to use a steel-concrete composite structure.
In the steel-concrete composite structure, a node is a key part for forming a frame structure, and particularly, under the action of seismic force, when the structure enters a plastic stage, the node plays a key role in the integrity and the structure of the whole structure. The form of the node is divided according to the bending moment transmission effect and can be divided into a rigid connection node, a hinge joint node and a semi-rigid node; the method is divided into a reinforced ring type node, a bending-resistant reinforcing steel bar node, a ring beam node and a mixed node according to a bending moment transmission mode; the method is divided into a bearing pin type node, a shear web node, a shear ring node and the like according to a vertical shear force transmission mode; the core concrete can be divided into a non-through node and a through node according to whether the horizontal shearing force of the beam end is directly transmitted to the core concrete.
The overhanging structure is one of the common structural forms in engineering structures, such as a rain fly, a cornice, an outer balcony, a porch and the like in building engineering, and the structure is that a beam or a plate is overhung from a main structure to form an overhanging structure, and the overhanging structure is still a beam-plate structure essentially. At some building structure's part of encorbelmenting, because the particularity of structure, need to pass through the node with girder steel and concrete shear force wall and couple together to the requirement is effectively rationally transmitted the major structure with the part's of encorbelmenting power in, and guarantees good structural stability. The connection node of the steel beam and the concrete shear wall is not common in a building structure, and is a technical problem to be solved for a building structure engineer, and factors such as construction requirements, quality assurance requirements and the like need to be comprehensively considered.
