Abstract
The invention discloses a structure for preventing bolts connecting a steel plate shear wall with slits with a frame beam from slipping. Bolt holes for connecting an upper frame beam and a lower frame beam are formed on the upper and lower ends of the main steel plate with slits; the density and row number of the bolt holes at corners at the upper and lower ends of the main steel plate with slits are greater than those of the middle bolt holes; and the four edges of the main steel plate with slits are reinforced to form a closed system. Due to the targeted layout mode of the bolts connecting the steel plate shear wall with slits with the frame beam and the closed edge reinforcing system, the bolt slipping is prevented or delayed, the noise caused by the bolt slipping is eliminated, relatively loss of high earthquake resistance of the steel plate shear wall with slits caused by the bolt slipping is avoided, and the field full-bolt connection of the steel plate shear wall with slits is ensured so as to enable disassembly and replacement after earthquake damage and protect the steel plate shear wall with slits from excessive vertical load. The closed edge reinforcing system also solves the problem of bolt slipping induced or intensified by unbalanced corners of the steel plate shear wall.
Description
Technical field
The invention belongs to technical field of structural engineering, particularly a kind of structure that prevents steel plate shear force wall bolt with seam slippage.
Background technology
The notion of steel plate shear force wall with seam equals proposition in 2002 by Japanese scholar Toko Hitaka the earliest.Its basic principle is: on steel plate, offer some perps; Make that steel plate band between perps (also claiming columnar part) is similar equally worked by curved pillar; Thereby with the former non-steel plate shearing that cracks is that main distortion changes into the distortion that steel plate bending with seam is the master, improves the distortion and the energy dissipation capacity of steel plate shear force wall with seam greatly.Steel plate shear force wall with seam also has rigidity adjustable (through the seam parameter), space layout advantages such as (only not being connected with beam with pillar) flexibly, is a kind of good energy dissipation member therefore.
Therefore steel plate shear force wall with seam can only not be connected with Vierendeel girder with frame column, compares the offering of its architectural door and window hole of being more convenient for traditional lateral resistant member such as cross support.And when being connected,, must take on-the-spot high-strength friction-type bolt to connect for making its construction install convenience (especially avoiding on-the-spot overhead welding) with Vierendeel girder.
Take high-strength friction-type bolt connection also can reduce shear wall and bear the vertical load that floor and body of wall transmit through the time of twisting at the end of bolt; Avoid shear wall because of bearing the excessive unstability too early of vertical load, thereby improve the total number of plies of building that it was suitable for greatly.
Steel plate shear force wall with seam and Vierendeel girder are the replacing that makes things convenient for after its big shake destroys through bolted another benefit of high-strength friction-type.
In sum, to take on-the-spot high-strength friction-type bolt to be connected with Vierendeel girder be the important assurance that makes its advantage be able to give full play to steel plate shear force wall with seam.
But correlation test and analysis show: steel plate shear force wall with seam bight is because of bigger overturning moment and the horizontal shear of burden simultaneously, and corners is prone to unstability, and therefore slippage takes place easily for the friction-type high-strength bolt here.
Steel plate shear force wall high-strength bolt slippage adverse effect with seam does not also cause at present enough attention, but relevant large scale member shock test shows and slides onto that I haven't seen you for ages brings following two serious problems:
1) brings noise high-frequency, shrillness, make the user be difficult to bear;
2) cause steel plate wall with seam with the upper and lower fixing clearance scope of Vierendeel girder in rotate, thereby and then the junction plate of extruded frame beam cause its bight unstable failure, and the bight unstability can reduce its bearing capacity and distortion and energy dissipation capacity.
For the slippage of steel plate shear force wall with seam and Vierendeel girder connecting bolt, external as Japan mainly realizes preventing its slippage through the friction factor of taking special material and technology to increase the steel plate junction to contact surface.But also difficult the reaching through the measure that increases friction factor of domestic existing material and technological level prevents its slippage, therefore needs to seek other and prevents the method for bolt slippage.
From existing achievement in research, domestic also not have an achievement in research of being correlated with." two side connection large-space vertical seam-opening combined steel plate shear wall " like one Chinese patent application CN200810034318.6; " combined steel plate shearing force wall with large aspect ratio " of one Chinese patent application CN200810034317.1; " two-side-connection combined steel plate shearing force wall " of one Chinese patent application CN200810034316.7; The bolt arrangement of shear wall has been taked conventional arrangement form in the above-mentioned patent, does not take special construction measure to the bolt slippage.Test shows that this kind connection very likely can produce the slippage problem of bolt, and the bolt slippage not only brings huge noise but also can cause the greater loss of member ductility and energy-dissipating property.
Summary of the invention
The objective of the invention is to propose a kind of structure that prevents steel plate shear force wall bolt with seam slippage, thereby prevent or delay to connect steel plate shear force wall with seam and the bolted slippage of the high-strength friction-type of Vierendeel girder.
Technical scheme of the present invention is:
Arrangement form to steel plate shear force wall with seam and Vierendeel girder connecting bolt changes, and adopts non-homogeneous layout---and promptly the bolt to steel plate shear force wall corners with seam carries out local targetedly the reinforcement; Simultaneously, through the measure of putting more energy into of careful edge the bight of steel plate wall with seam is strengthened to prevent causing the bolt slippage because of the bight unstability of steel plate wall with seam.Be that the present invention takes all factors into consideration bolt arrangement form and the corners detail measure of putting more energy into and realizes preventing the slippage of steel plate wall with seam and Vierendeel girder connecting bolt.
Particularly; A kind of structure that prevents steel plate shear force wall with seam and the slippage of Vierendeel girder connecting bolt of the present invention; Band perps main steel plate upper and lower side is offered respectively to set a roof beam in place with upper and lower frames and is connected the bolt hole of usefulness; Described bolt hole adopts non-homogeneous arrangement form, promptly arranges from row's number and density aspect all the bolt hole greater than the middle part with the bolt hole of perps main steel plate upper and lower side corners; Said steel plate wall with seam edge is established and is put more energy into, and is put more energy in the edge to form the system of sealing through detail measure.
Further, the bolt hole of said band perps main steel plate upper and lower side corners is 2～4 arranged, and every row establishes 2～4 bolts hole; The middle part bolt hole is single layout.
The spacing of the bolt hole of described band perps main steel plate upper and lower side corners is less than the spacing of middle part bolt hole.
The edge system of putting more energy into of described sealing comprises that longitudinal edge is put more energy into and transverse edge is put more energy into.
Described transverse edge is put more energy into and is comprised that being located in steel plate upper and lower side with seam and upper and lower frames sets a roof beam in place and go up the two clamping plates of lower connecting plate both sides.
Described clamping plate lateral surface center line adds web along its length, makes these clamping plate T-shaped.
The corresponding band of said clamping plate perps main steel plate upper and lower side bolt hole is offered connecting through hole, and is connected through lower connecting plate on bolt and the Vierendeel girder.

The described longitudinal edge employing shaped steel of putting more energy into.
Said shaped steel cross section is flute profile or worker's shape or rectangle etc.
The present invention takes the principle of above-mentioned measure to resolve as follows:
1) taking local reinforcement the in 2～4 bolt scopes of limit portion, is because the relative middle part of overturning moment that steel plate wall with seam is shared in the bight and horizontal shear is much bigger.Wherein the concrete reinforcement width of 2～4 bolt scopes obtains on verification experimental verification and numerical simulation analysis basis.
What 2) the bigger overturning moment in bight caused is the vertical slippage of bolt rubbing surface, and the effective measures that overcome vertical slippage are to increase bolt row number, rather than pure the dependence increases bolt specification or reduce pitch of bolts;
What 3) the bigger horizontal shear in bight caused is the horizontal sliding of bolt rubbing surface, overcomes the bolt horizontal sliding and then relies on and encrypt bolt promptly to reduce pitch of bolts the most effective.
4) T clevis plate simultaneously also is that the horizontal edge of steel plate wall with seam is put more energy into; Steel plate wall two side ends with seam is logical high vertically puts more energy into and puts more energy into being arranged at the upper and lower frames longitudinal edge that the capping plate of going up the lower connecting plate two side ends becomes steel plate wall with seam of setting a roof beam in place; And horizontal edge is put more energy into the vertical edges edge that the formed sealing system of putting more energy into of putting more energy into, and the characteristic of this system of putting more energy into is that corners all has accordingly and to put more energy into.
5) the edge system of putting more energy into of sealing can avoid the corner unstability of steel plate wall with seam; And the corner unstability not only has great adverse effect to the performance of steel plate shear force wall with seam; But also can cause or aggravate the bolt slippage of steel plate wall with seam; And the bolt slippage can cause more serious corner unstability, promptly forms vicious circle.
6) because there are certain coupling in bolt slippage and corner unstability; Be that the corner unstability can cause the bolt slippage; And the bolt slippage can aggravate the corner unstability; Therefore the effective measures that overcome the bolt slippage not only will start with from the bolt layout, in the limit portion of slippage easily bolt is carried out part strengthens, but also will the corner unstability that possibly bring out or aggravate the bolt slippage be limited, i.e. the edge that formation the is sealed system of putting more energy into.
Beneficial effect of the present invention
