Description

Connecting structure of high-large-span beam column and buckling restrained brace structure

Technical Field

The utility model relates to a bearing structure between beam column, in particular to buckling restrained brace structure's that sets up connection structure between beam column of high large-span.

Background

Some buildings (structures) adopt reinforced concrete beam columns to bear frame structures of all loads, when the height between floors of the frame structures is too high and the span is too large, the defects of poor shearing resistance and weak seismic resistance exist, in order to improve the shearing resistance and the seismic resistance, a shear wall structure or a steel cylinder structure is generally adopted, but in a construction site, the situation that the shear wall structure with stronger shearing resistance or the cylinder structure cannot be adopted due to special occasion bay and space limitation, such as facilities of movie theaters, gymnasiums and the like, can be met; in order to meet the functional requirements of buildings and simultaneously strengthen the shock resistance of the buildings, a buckling restrained brace structure is adopted to realize the tie between frame beams and columns; the structural principle of the buckling restrained brace structure is as follows: the buckling restrained brace structure is composed of a core plate, an outer sleeve and a filling material, wherein the core plate is generally a cross-shaped steel plate, the core plate is welded with other components through connecting steel plates at two ends of the core plate, and bears all rigid loads, a flexible filling material is arranged between the outer sleeve and the core plate, and the outer sleeve and the filling material only restrain the buckling of the core plate under pressure, so that the core plate can enter a yielding state under tension or pressure, the integral stability of a connected beam column is improved, and the buckling restrained brace has a good hysteretic performance; the buckling restrained brace structure aims at improving the seismic performance of the brace, and reduces or even avoids the damage of the main body in the earthquake through the self rigidity and hysteretic energy consumption generated before the main body of the structure yields; the buckling restrained brace structure has definite yielding bearing capacity, can play the role of a fuse under a large earthquake, is used for protecting the main body structure from yielding or seriously damaging under the large earthquake, and can be conveniently replaced by checking after the large earthquake, so that the buckling restrained brace structure is arranged, the shock resistance of the structure can be improved, and the appearance size of the brace can be reduced.

The steel plates at two ends of a core plate in the traditional buckling restrained brace structure realize the opposite pulling of a beam column through welding embedded part steel plates pre-embedded in the beam or the column, the traditional embedded part steel plates are generally in a T-shaped structure, a top steel plate exposed out of concrete is welded with the end of the core plate, a bottom plate of the T-shaped structure is pre-embedded in the concrete of the beam or the column, and the pre-embedded connection structure has the defect of weak anti-falling strength; in addition, the buckling restrained brace structure is a combination part of a beam and a column of the frame structure, and embedded parts in the beam and embedded parts in the column are respectively arranged and are not connected with each other, so that the embedded parts resist respective pulling force, a stable triangular brace structure cannot be formed, and better integral shearing resistance cannot be exerted.
