Description
Technical field
The utility model 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: offer some perps on steel plate, make that steel plate band between perps (also claiming cylindrical portion) 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 (by 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 by 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 by 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 its advantage is given full play to steel plate shear force wall with seam.
But correlation test and the analysis showed that: steel plate shear force wall with seam bight is because of bigger overturning moment and the horizontal shear of burden simultaneously, and corner portion is prone to unstability, and therefore slippage takes place friction-type high-strength bolt herein easily.
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 by the friction factor of taking special material and technology to increase the steel plate junction to contact surface.But also difficult the reaching by 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 " as Chinese patent application CN200810034318.6; " combined steel plate shearing force wall with large aspect ratio " of Chinese patent application CN200810034317.1; " two-side-connection combined steel plate shearing force wall " of Chinese patent application CN200810034316.7; The bolt arrangement of shear wall has been taked conventional arrangement form in the above-mentioned patent, and special construction measure is not taked in slippage at bolt.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.
