Dual-core visual inspection buckling restraint support

Abstract

The invention discloses a dual-core visual inspection buckling restraint support. The dual-core visual inspection buckling restraint support comprises two energy consumption inner core panels, two sets of end stiffening plates, two end connecting plates, a plurality of sets of connecting positioning plates and a peripheral restraint component; the two energy consumption inner core panels are arranged in parallel in the panel thickness direction, the end stiffening plates are rectangular plates, the two opposite sides of each set of end stiffening plates are perpendicularly and fixedly connected with the parallelly-arranged energy consumption inner core panels, and the other sides of the end stiffening plates and the end sides of the energy consumption inner core panels are located in the same plane; the end connecting plates are fixedly connected with the end sides of the two energy consumption inner core panels and one sides of the end stiffening plates; and the connecting positioning plates are also rectangular plates, in the parallelly-arranged energy consumption inner core panels, the two opposite sides of the connecting positioning plates are perpendicularly and fixedly connected with the energy consumption inner core panels, and all the connecting positioning plates are located in the same plane and distributed at equal intervals.

Description

Technical field [0001] The invention belongs to the field of civil engineering and relates to a buckling restraint support for reducing the seismic response of an engineering structure. Background technique [0002] Before the 1990s, the traditional method of structural seismic resistance was to dissipate seismic energy through local yielding of the main structure, such as beam hinge mechanism. This seismic energy dissipation method caused damage to the main structure of the structure, which seriously increased the difficulty and cost of post-earthquake repair. Conducive to the post-earthquake repair of the structure. Since the Hanshin Earthquake in Japan and the Northridge Earthquake in the United States, the buckling restraint brace has been rapidly promoted and applied in developed countries such as Japan and the United States as an energy-dissipating component with superior performance, and research in my country is also under development. stage. The buckling restraint suppo...

Problems solved by technology

[0002] Before the 1990s, the traditional anti-seismic method used to dissipate the seismic energy through the local yield of the main structure, such as the beam-hinge mechanism. Conducive to post-earthquake repair of structures

The buckling restraint support of the all-steel peripheral restraint section is adopted, such as the public patent CN101974947B or CN101718123B, the core member of which is a steel member such as I-shaped steel, and the flange and web of the I-shaped section are restrained by the peripheral all-steel restraint member at the same time. The connection welds or chamfers between the flange and the web of the profiled section conflict with the peripheral constraining members, making it more difficult to fabricate buckling constrained supports

Moreover, the outer constrained steel members are closely attached to the inner core members, resulting in a reduction in the overall stiffness of the constrained members, reducing the efficiency of the steel used in the constrained members

[0004] In addition, if the restraining members of the buckling-restrained braces are close to the inner core members, the restraint members can only be disassembled for visual inspection of the buckling-restrained braces after the earthquake, and the damage of the buckling-restrained braces cannot be quickly observed, which affects the buckling-restrained braces.
