Description
Technical field
The utility model is related to one kind to exempt from the anti-shear buckling steel plate shear force wall of bearing capacity, belongs to building engineering field, can be wide
The general Lateral Resistant System applied to all kinds of steel buildings.
Background technology
In high-rise building steel structure, the Lateral Resistant System for resisting the horizontal forces such as wind load, geological process mainly has
Concrete shear force wall, bracing members, steel plate shear force wall etc..
Concrete shear force wall is stringent to structure lateral displacement requirement when steel construction is used together, and steel construction anti-side ductility is good
Advantage can not play.Bracing members have preferable lateral resistance behavior, but support the connecting node construction between beam column complicated, use steel
Amount is big, and makes high processing costs, and site operation error is big.Buckling occurs under bracing members geological process, bearing capacity is with sidesway
Increase and decrease sharply, anti-seismic performance is bad.
Steel plate shear force wall is since component form is simple, and connecting node is easy to implement, stress performance is excellent etc., widely should have
Use prospect.
In the second stage of Aseismic Design, it is desirable to which steel plate shear force wall has preferable plastic deformation to consume more seismic energies
Amount.And vertically and horizontally scale is larger for steel plate shear force wall, steel plate thickness is relatively thin, it is easy to unstability occur and cause bending resistance and resistance to compression
Bearing capacity drastically declines, and shear-carrying capacity is then able to a part of reservation by developing the oblique pull field of force, but the oblique pull field of force pair with
Connected pillar be applied with very big lateral load, pillar has in itself by stretch bending and occurs the possibility of torsional outside plane.
It is currently used there are two ways to prevent steel plate shear force wall unstability.The first is to set to add on steel plate shear force wall
Strength rib has the ribbed stiffener of both direction in length and breadth, needs to set according to calculating, and steel plate shear force wall is divided into lattice, reduces wide
Thickness rate improves buckling bearing capacity.Second method is the fixing concrete plate on the outside of steel plate shear force wall, utilizes the firm of concrete slab
It spends to constrain steel plate shear force wall, avoids the buckling of steel plate shear force wall.
The stiffened steel plate shear wall of first method description, ribbed stiffener weld together with steel plate shear force wall, horizontal masterpiece
With lower ribbed stiffener and steel plate shear force wall cooperative bearing, cooperative transformation.This steel plate shear force wall rigidity is big, absorption pressure, thus holds
Easy compressive buckling, the plastic deformation ability of the steel of steel plate cannot preferably be carried out.
The concrete constraint steel plate shear force wall of second method description, in order to solid well between concrete slab and steel plate
It is fixed, it is necessary on steel plate shear force wall perforate or weld bolt, both sides concrete slab is fixed on steel plate wall by bolt.It is this
Construction connection is complicated, it is necessary to make finished product member in factory, and transport and installation requirement are high.
According further to《Technical Specification for Steel Structure of Tall Buildings》(JGJ99-2015) requirement, steel plate shear force wall are preferably pressed
It is not subject to vertical load design.In the construction process, ensure that it does not hold with the mode welded after girder steel frequently with steel plate shear force wall
By excessive vertical load, this brings postponing for duration to construction, and cannot thoroughly exempt steel plate shear force wall bear it is subsequent
Dead load and mobile load are also subjected to certain vertical load and moment of flexure in structure during by lateral force.
Utility model content
In order to solve the problems, such as present in background technology, the utility model provides one kind and exempts from the anti-shear buckling steel of bearing capacity
Plate shear wall, it fully achieves the requirement for being not subject to vertical load that JGJ99-2015 proposes steel plate shear force wall；Construction letter
Single, low cost, does not influence the site operation duration；Steel plate shear force wall can be avoided to bear vertical load, while steel plate will not go out
Existing local buckling, so as to improve the shear-carrying capacity of steel plate wall, enhances the ductility and energy dissipation capacity of steel plate wall.
