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...
