Description

A kind of back-shaped control power buckling-resistant support structure
Technical field
The utility model belongs to building structure field, is related to a kind of back-shaped control power buckling-resistant support structure.
Background technique
Lateral resisting structure plays the role of resisting the horizontal loadings such as wind load and earthquake load in building structure, is to guarantee The safe and reliable key of total.The lateral resisting structure applied in multi and tall steel building at present mainly has support construction and steel Two class of plate shear wall structure, and according to the difference of stress performance and structural form, but can be subdivided into central supported, accentric support, Buckling restrained brace (anti-buckling support), non-stiffened steel plates wall, stiffened steel plates wall, crack steel plate wall and anti-buckling steel plate wall etc. are more Kind form.
The anti-flexion capabilities of central supported are poor, especially elasticity or bullet can inevitably occur under middle shake and big shake effect Plastic buckling causes support to be failed, and causes the decline of the rigidity of structure and energy dissipation capacity, influences structure safety.Accentric support passes through branch Support biasing forms energy consumption coupling beam and consumes energy, and can be relieved the buckling problem of strut, but horizontal loads lower floor plate can be relatively early Ground destroys, and to guarantee that active beam link is surrendered first, remaining component generally requires to be designed to excessive section or even mistake Divide superpower, increase construction cost, practical application is relatively limited.Buckling restrained brace is by constraining material in support core material outer cladding Material or component belong to " construction is anti-buckling " scope, its anti-buckling energy to reach a kind of support for limiting core material buckling effect Power is stronger also to have better energy dissipation capacity, but such supports universal section larger, need to occupy more spaces, and structure Complex, project cost height is made, therefore there is biggish limitation in practical engineering applications.
Steel plate shear force wall (non-to put more energy into, put more energy into, is anti-buckling) provides rigidity by the pulling force field that wallboard is formed and resists horizontal force, But pulling force field has very unfavorable oblique effect to the edge constraint column (frame columns) of steel plate wall, and due to wallboard nonreactive pressure energy Power, tilting moment caused by horizontal loading is mainly formed by couple by frame column axial force and resists, so that internal force is very big in column, Easily lead to the unstability or destruction of frame columns, it is therefore desirable to which the additional column section or selection steel core concrete column etc. of increasing is stablized The better composite structure column of property is as edge constraint component, the application which also limits steel plate shear force walls in steel construction.Separately Outside, frame beam bending deformation in the case where upper and lower level wallboard is formed by pulling force field action can be largely suppressed, similar By " build-in ", so that frame beam plasticity is insufficient, frame columns often form plastic hinge, Aseismic Design prior to frame beam In " strong column and weak beam " requirement it is relatively difficult to achieve, reduce the anti-seismic performance of structure entirety.In addition, the wallboard of steel plate shear force wall need to be Construction site is attached by bolting or welding with frame beam column, heavy workload and quality of connection is not easy to guarantee, hampers steel The assembling application of slab-wall structure.Influence of the slotted steel plate shear wall wallboard to side column is small, but since rigidity and bearing capacity are weaker, Practical application is seldom.
