Problems solved by technology

The foundation has strong compressive capacity and weak tensile capacity, making it difficult to guarantee safety
In the case of significant tensile, bending and shearing forces, foundation design is extremely difficult, which greatly limits the application of buckling-resistant braces in high-rise buildings, and becomes a bottleneck in the popularization and application of buckling-resistant braces

Embodiment 1

[0038]Embodiment 1: The present invention is used in reinforced concrete structures, frame 1 is a reinforced concrete frame, and anti-buckling support 2 is installed between the frame column 4 and the frame beam 6 of the middle span of the reinforced concrete frame, through the anti-buckling support 2 The special structure avoids the problem of buckling of the central reinforced concrete frame under compression, and can yield without buckling under tension and compression, which can better consume the seismic energy input into the structure. The connection between the bottom end of the frame column 4 of the reinforced concrete frame without anti-buckling support 2 and the foundation 3 adopts the fixed end F, and the connection between the bottom end of the frame column 4 of the reinforced concrete frame with the anti-buckling support 2 and the foundation 3 adopts Embedded end M. Embedded parts are provided on the bottom and surrounding surfaces of the frame column 4 of the rei...

Embodiment 2

[0039] Embodiment 2: The present invention is used in a steel structure. The frame 1 is a steel frame, and an anti-buckling support 2 is installed on the middle span of the steel frame. Through the special structure of the anti-buckling support 2, buckling of the steel frame in the center is avoided. The problem is that it can yield but not buckle under tension and compression, and can better dissipate the seismic energy input into the structure. The connection between the bottom end of the frame column 4 of the steel frame without anti-buckling support 2 and the foundation 3 adopts the fixed end F, and the connection between the bottom end of the frame column 4 of the steel frame with anti-buckling support 4 and the foundation 3 adopts embedding End M. Embedded parts are provided on the foundation 3 which is in contact with the bottom end of the frame column 4 of the steel frame on which the anti-buckling support 2 is installed. The steel frame installed with the anti-buckl...

Abstract

Disclosed are a swinging buckling restrained brace and frame structure system and a construction method thereof. The swinging buckling restrained brace and frame structure system comprises a buckling restrained brace, a frame, a foundation, fixing ends and embedded ends, the buckling restrained brace is mounted on the frame, and the frame is fixed onto the foundation by the aid of the fixing ends and the embedded ends. The swinging buckling restrained brace and frame structure system and the construction method are mainly characterized in that restraint on the fixing ends of columns of the frame with the brace and restraint on the foundation are released, and the embedded ends of an energy consuming element are vertically disposed. The system is high in structural rigidity, and seldom moves when in earthquake, energy consuming and damping effects are good, and the buckling restrained brace which is used as a replaceable energy dissipation unit can be conveniently replaced after earthquake.

Description

technical field [0001] The invention relates to the technical field of civil engineering structures, in particular to a swing anti-buckling support-frame structure system and a construction method thereof. Background technique [0002] The traditional seismic design method allows the structure to enter a nonlinear state during a strong earthquake, relying on the elastic-plastic deformation of the main structure and components to dissipate the energy input by the earthquake, so as to realize the building structure "not damaged by small earthquakes, repairable by moderate earthquakes, and Not fall" earthquake fortification target. However, during the earthquake, structures and components are subject to complex reciprocating loads, making it difficult to quantitatively determine the degree of cumulative damage, resulting in the difficulty of post-earthquake repair of most damaged structures, which have to be demolished and rebuilt, resulting in a huge waste of funds and resourc...
