Buckling restrained energy-consumption supporting device of building frame structure

Abstract

The invention relates to a buckling restrained energy-consumption supporting device of a building frame structure, which consists of an energy-consumption steel tube (1), an inner restraining steel tube (2), an outer restraining steel tube (3) and connecting steel plates (4 and 5). Corrugations are formed on the outer side of the wall of the energy-consumption steel tube (1) at certain intervals, two ends of the energy-consumption steel tube (1) are respectively connected onto the connecting steel plates (4 and 5), and the inner restraining steel tube (2) and the outer restraining steel tube (3) are placed on the inner side and the outer side of the energy-consumption steel tube (1). The buckling restrained energy-consumption supporting device of the building frame structure has the advantages of high rigidity and deformation ability, easiness in control of buckling, avoidance of buckling instability and high energy consumption ability, and is accurate in stress, simple in structure, convenient in manufacture, easy in installation and maintenance and fine in durability. The buckling restrained energy-consumption supporting device can be used for buildings with multilayered and high-rise concrete structures and buildings with steel structures, and resolves the problem of insecurity of the structures of the buildings in violent earthquake.

Description

technical field [0001] The invention relates to the technical field of buildings, in particular to an anti-buckling energy-dissipating support device for a building frame structure. Background technique [0002] In the field of anti-seismic building structures, the frame-bracing structure is an effective anti-seismic system, which can increase the anti-sway stiffness of the building structure and reduce the bending moment and shear force of the frame columns, beams, and so on. The supporting members of the frame-supporting structure generally consist of steel sections. Sectional steel rods are a very good material for bearing tension, but when they are under pressure, they have the problem of buckling and instability. Due to the reciprocating action of the earthquake force, the internal force of the supporting member has to undergo a process of constant change of tension and pressure. Under the action of pressure, once the supporting member buckles and loses stability, the ...

Problems solved by technology

Sectional steel rods are a very good material for bearing tension, but when they are under pressure, they have the problem of buckling and instability.

Due to the reciprocating action of the earthquake force, the internal force of the supporting member has to undergo a process of constant change of tension and pressure. Under the action of pressure, once the supporting member buckles and loses stability, the supporting system will fail and endanger the safety of the building.
