Description
Technical Field
The utility model belongs to the building structure field relates to a stride accuse power buckling restrained eccentric supporting structure more.
Background
The lateral force resisting structure plays a role in resisting horizontal loads such as wind load, earthquake load and the like in the building structure, and is the key for ensuring the safety and reliability of the whole structure. The lateral force resisting structure applied to the multi-story and high-rise steel structure at present mainly comprises a support structure and a steel plate shear wall structure, and can be subdivided into forms of a central support, an eccentric support, a buckling restrained brace (buckling restrained brace), a non-stiffened steel plate wall, a slotted steel plate wall, a buckling restrained steel plate wall and the like according to different stress performances and different structural forms.
The buckling resistance of the central brace is poor, and particularly, under the action of medium and large earthquakes, elastic or elastic-plastic buckling inevitably occurs to cause failure of the brace, so that the structural rigidity and the energy consumption capability are reduced, and the structural safety is influenced. Traditional eccentric bracing forms the power consumption through supporting the biasing and links the roof beam and consume energy, thereby the power consumption roof beam section takes place to provide the buckling problem of vaulting pole for the vaulting pole after great deformation for the vaulting pole, nevertheless power consumption roof beam section warp and just means that the floor can take place to destroy earlier to for guaranteeing that power consumption roof beam section is at first yielded, all the other components often need design into too big cross-section, and is excessive superstrong even, increases construction cost, and practical application is comparatively limited. The buckling restrained brace is a brace which can limit the buckling effect of a core material by coating a restraining material or a member outside a brace core material, belongs to the category of 'structural buckling prevention', has stronger buckling resistance and better energy consumption capability, but has larger general section, needs to occupy more building space, has more complex structure and high engineering cost, and has larger limitation in practical engineering application.
The steel plate shear wall (non-stiffened, stiffened and anti-buckling) provides rigidity to resist horizontal force through a tension field formed by the wall plate, but the tension field has a very unfavorable oblique effect on a side column of the steel plate wall, and because the wall plate has no pressure resistance, the overturning moment generated by horizontal load is mainly resisted by a couple formed by axial force of the side frame column, so that the internal force in the column is very large, instability or damage of the side frame column is easily caused, therefore, the column section needs to be additionally increased or a composite structure column with better stability such as a steel pipe concrete column needs to be selected as an edge constraint component, and the application of the steel plate shear wall in a steel structure is also limited. In addition, the frame beam can be restrained to a great extent under the tensile force field effect that upper and lower floor's wallboard formed, and the similarity receives "builds in" for frame beam plasticity development is not abundant, and the frame post often can form the plasticity hinge earlier than the frame beam, and the requirement of "strong post weak beam" is difficult to realize in the antidetonation design, has reduced the holistic anti-seismic performance of structure. In addition, the wall plate of the steel plate shear wall needs to be connected with the frame beam column through bolting or welding on the construction site, the workload is large, the connection quality is not easy to guarantee, and the assembly application of the steel plate wall structure is hindered. The slotted steel plate shear wall plate has little influence on the side columns, but has little practical application due to weak rigidity and bearing capacity.
In addition to the above disadvantages, the current lateral force resistant structure also affects the realization of the building function. Daylighting, ventilation and satisfying personnel's discrepancy needs are the most basic functional requirement of building through arranging door and window, but no matter support or steel sheet shear wall structure, all need occupy whole wall usually, seriously influence the arrangement of door and window entrance to a cave. The defect is particularly prominent in multi-story and high-rise steel structure residential buildings and fabricated steel structure residential buildings. The existing lateral force resisting structure, no matter a supporting structure or a steel plate shear wall structure, usually occupies the whole wall space, so that doors and windows are difficult to open on the wall surface of the lateral force resisting structure, and the influence of a black room on building use is caused. The influence on multi-story and high-rise steel structure residential buildings and assembled residential buildings is particularly prominent, the residential building column distance is small, the house type is variable, the lighting and ventilation requirements are higher, the wall surface without opening doors or windows is few, and therefore the existing lateral force resisting structure is difficult to meet the diversity requirements of building layout.
