Background
The steel reinforced concrete composite structure is a novel structure developed on the basis of a steel structure and a reinforced concrete structure. Compared with a reinforced concrete structure, the steel reinforced concrete composite structure can reduce the dead weight of the structure, reduce the earthquake action, reduce the section size of the member, increase the effective use space, reduce the foundation cost, save the formwork erecting process and the formwork, shorten the construction period, increase the ductility of the member and the structure and the like. Compared with a steel structure, the steel reinforced concrete composite structure can reduce the steel consumption, increase the rigidity, increase the stability and the integrity, enhance the fire resistance and the durability of the structure and the like. Therefore, the steel reinforced concrete composite structure has the advantages of both a steel structure and a concrete structure, and has obvious technical and economic benefits and social benefits.
The section steel-concrete combined structure is formed by combining section steel and concrete, and mainly transfers shearing force through a shearing-resistant connecting piece at an interface between the section steel and the concrete. The shear resistant connecting piece is a key component for combining the section steel and the concrete to work, and not only transfers the longitudinal shear between the section steel and the concrete, but also plays a role in preventing the section steel and the concrete from being vertically separated. Shear connectors are available in many forms and can be generally classified into two categories, rigid connectors and flexible connectors, according to their deformability. The rigid connecting piece comprises connecting pieces such as square steel, T-shaped steel, horseshoe-shaped steel, channel steel and the like; the stud, the bent rib, the angle steel, the anchor ring, the friction type high-strength bolt and the like belong to flexible shear connectors. Rigid shear connectors are commonly used in structures where shear redistribution is not a concern, the latter being widely used in general building construction and bridges. However, the shear rigidity and the strength of the shear connector are low, the number of the connectors is large, the cost is high, the connector interval is small, concrete pouring is inconvenient, the construction is complex, and the construction efficiency is affected.
