Embodiment

[0021] A new type of steel-concrete composite coupling beam with steel plates set on both sides, that is, the outer steel plate-concrete composite coupling beam, the concrete coupling beam is poured inside the outer steel plate, and the concrete and the steel plate are strengthened by studs. The studs are welded on the inner side of the double-layer steel plate, perpendicular to the steel plate, and arranged in several rows evenly along the height direction of the steel plate. The outer covering steel plate is enclosed by four steel plates on four sides to form an outer covering formwork, and the concrete is wrapped in the covering formwork. The concrete adopts high-strength concrete (above C6).

[0022] This new type of composite coupling beam provides flexural strength and shear strength by arranging steel plates on the outside of the coupling beam instead of closely matched longitudinal and transverse steel bars, which is beneficial to exert the ductility of the structure and ...

Abstract

The invention provides a steel plate and high-strength concrete combination connecting beam which comprises wrapping steel plates and high-strength concrete poured among the wrapping steel plates. According to the steel plate and high-strength concrete combination connecting beam, the steel plates are arranged outside a concrete connecting beam to substitute shear reinforcements to resist a shearing force with the concrete, and the shear resistance of the connecting beam is improved. In addition, the wrapping steel plates have an effective constraint effect on the high-strength concrete, the brittleness of the high-strength concrete can be improved, and the carrying capacity and deformability of the connecting beam are improved, so that the earthquake resistance of a coupled shear wall structure system is ensured, and the cross section of the connecting beam is decreased. As the wrapping steel plates serve as templates, the construction is more convenient and quicker.

Description

Technical field [0001] The invention belongs to the technical field of steel and concrete composite structures and hybrid structures, and relates to a shear wall coupling beam, in particular to a steel plate high-strength concrete composite coupling beam. Background technique [0002] Coupling beam refers to the beam that connects the wall leg and the wall leg in the shear wall structure system. It is an important seismic energy dissipation component in high-rise buildings. Under the action of horizontal earthquake, the coupling beam can adjust the lateral rigidity and bearing capacity of the shear wall and ensure the ductility of the shear wall through its own yield, so as to achieve the purpose of consuming seismic capacity. The strength, stiffness and deformability of the coupling beam have a significant impact on the seismic performance of the structure. [0003] The failure of connecting beams in high-rise building shear walls under horizontal load can be divided into brittle...
