Description
Technical field
The present invention relates to a kind of steel plate shear force walls, belong to construction project technical field more particularly to a kind of vertical load of reduction
The circular-arc cut stiffened steel plate shear wall that lotus influences.
Background technology
Steel plate shear force wall is a kind of novel lateral resistant member to grow up the 1970s, according to structural form difference
Steel plate shear force wall can be divided into five classes：Non- stiffened steel plate shear wall, stiffened steel plate shear wall, anti-buckling steel plate shear force wall, steel
Board group combination shearing wall and slotted steel plate shear wall.Compared to reinforced concrete shear wall, the size of steel plate shear force wall is small, dead weight
Gently, increase the usable floor area in house, reduce foundation cost, is good in economic efficiency, while its also big, shearing resistance carrying with anti-side rigidity
The feature that power is high, ductility is good and energy dissipation capacity is strong, therefore, steel plate shear force wall become most promising high-rise lateral resisting
One of system.
Existing JGJ/T380-2015《Steel plate shear force wall technical regulation》Middle regulation：Steel plate shear force wall is preferably by being not subject to erect
It is calculated to load design, and should calculation assumption be realized using corresponding construction and working measure.Vertical load can make steel of putting more energy into
The embedded steel plate of plate shear wall generates that drum is bent, this lateral resistant ability, anti-side rigidity and energy dissipation capacity to stiffened steel plate shear wall
It will produce adverse effect.It is usual in engineering practice in order to realize that steel plate shear force wall is not subject to the calculation assumption of vertical load
Way is main body frame of first constructing, and waits for that main body binds and main dead load has applied the peace for finishing and then carrying out embedded steel plate
Dress, there are following problems for this kind of way, when, construction period can be extended；Second is that under wind action, without steel plate
Shear wall, which provides lateral resisting, can cause building structure deformation excessive；Third, the additional dead load such as finishing layer and working load are
Installed in embedded steel plate after-applied, vertical load can be still transmitted on steel plate shear force wall.Another method is by embedded steel plate
Installation lag behind main body frame number layer, compared with a kind of upper method, this kind of way short construction period, and in the construction process,
Structure has certain anti-side rigidity, but basic problem is the stiffened steel plate shear wall still vertical lotus in unavoidable commitment part
It carries.
It is required according to the prior art, steel plate shear force wall should not bear the vertical load in addition to dead weight, this sets actual
Meter, construction and in be it is difficult to ensure that, therefore, it by the adverse effect of vertical load is always to build to avoid steel plate shear force wall
The problem in field.
If Chinese patent (203716336 U of Authorization Notice No. CN) discloses " a kind of side punch thin steel plate shear wall ",
Including frame column disposed in parallel, a pair of frames beam, frame column and Vierendeel girder are at least set between frame column disposed in parallel
It is connect respectively (except the position that punches) with embedded sheet metal, ribbed stiffener is symmetrically arranged in the embedded sheet metal place of punching both sides.The hair
It is bright that embedded sheet metal can be given to provide stronger supported along four sides, steel plate shear force wall " pulling force field " effect can be given full play to, is had very
High side bearing capacity；" pulling force field " can be greatly reduced to the additional bending moment of frame column, effective protection frame column simultaneously.The steel
Plate shear wall is that sufficient " pulling force field " can be formed in the case where significantly reducing side bearing capacity, is substantially not drop substantially
The steel column of shear wall both sides is protected under the premise of low steel plate shear force wall side bearing capacity, but is being constructed for stiffened steel plate shear wall
It can be influenced do not have improvement by vertical load in the process with use；In addition, the steel plate shear force wall on embedded sheet metal to opening up
Hole specifications parameter etc. also do not relate to, and this exactly influences the key factor of steel plate shear force wall side bearing capacity.
Invention content
The object of the present invention is to provide a kind of circular-arc cut stiffened steel plate shear walls that reduction vertical load influences, and are used for
Solve the problems of the prior art.
The present invention is achieved by the following technical programs：
A kind of circular-arc cut stiffened steel plate shear wall for reducing vertical load and influencing, including by frame column, Vierendeel girder structure
At agent structure, in agent structure installation embed steel plate, ribbed stiffener and embedded steel plate are using welding or high-strength bolt is connect, institute
It states embedded steel plate with frame column and Vierendeel girder to be connected, the embedded steel plate horizontal direction side offers circular-arc cut, circular arc
The arc length of shape notch is horizontal direction, camber is vertical, and the circular-arc cut is located at the middle part of embedded steel plate horizontal direction side.
In order to achieve the object of the present invention, it can also adopt the following technical scheme that：
The circular-arc cut stiffened steel plate shear wall as described above for reducing vertical load and influencing, the circular-arc cut
Arc length is the 1/3~1/4 of embedded steel plate span, camber ranging from 10~15cm of circular-arc cut.
The circular-arc cut stiffened steel plate shear wall as described above for reducing vertical load and influencing, the circular-arc cut are set
Set the upper side edge and lower side in embedded steel plate.
The circular-arc cut stiffened steel plate shear wall as described above for reducing vertical load and influencing, the circular-arc cut are set
Set the centre position in embedded steel plate horizontal direction side.
The as described above circular-arc cut stiffened steel plate shear wall for reducing vertical load and influencing, the embedded steel plate it is upper
2 circular-arc cut upper and lower correspondings that side and lower side are respectively set.
It is an advantage of the invention that：
1, the present invention is arc-shaped in embedded steel plate horizontal direction side namely the setting of embedded steel plate upper side edge or/and lower side
Notch, this construction measure can effectively weaken adverse effect of the vertical load to steel plate shear force wall limit lateral capacity；Added using this
Strength steel plate shear force wall can effectively shorten construction period, and preferable anti-side rigidity is provided for building structure.
2, by various optimization designs such as mechanics, structure and simulation test, steel is embedded in this stiffened steel plate shear wall
The circular lance size, the parameter selection range that are opened up on plate are scientific and reasonable, effect protrudes, and also can preferably avoid circular-arc cut
It is excessive, embedded steel plate shearing limit lateral capacity can be caused relatively low；Circular-arc cut is too small, and embedded steel plate can be made to undertake excessive erect
To load.
3, the present invention has structure simple structure, power transmission clear, is easily installed construction and use.
