Description
Technical field
The utility model belongs to building field, relates to multilayer and high-rise steel structure system, particularly a kind of semirigid frame-steel plate shear force wall structure.
Background technology
Node is connection and a power transmission hinge important in the framework, and the performance of total performance is played crucial effect.In traditional steel framed structure rigid joint use more, before Northridge earthquake in 1994, because of the steel frame that is welded to connect has necessary strength, ductility and reliability; Be considered to one of safest structure always; But in 6.7 grades of earthquakes of this time, a steel framed building destroys surplus in the of 200, and serious brittle fracture has taken place because of ductility is relatively poor many full welding rigid joints; Make people propose requirement, proposed semirigid frame thus the ductility of node.The node rotational characteristic of semirigid frame is between perfect rigidity and desirable have good ductility between hinged; Redistribution of internal force through moment of flexure can be optimized beam cross-section; Compare making and install simple and easy and rapid with traditional being rigidly connected of a large amount of welding of needs; And the saving steel using amount, the cost of reduction engineering.But because rigidity is relatively poor, compares with rigid frame and can produce bigger lateral deformation, be not suitable for being applied to separately multi-rise building.
The rigidity of frame construction is less relatively, and the height increase when structure when anti-side rigidity does not meet design requirement, can be provided with lateral resistant member in framework, improve the anti-side rigidity of structure, effectively reduces the sidesway of building.Common anti-side member has support, concrete shear force wall, steel plate shear force wall structure etc.Wherein, steel plate shear force wall has than supports and the more superior anti-seismic performance of concrete shear force wall.Be embodied in:
(1) under lateral forces; Surrender (thin plate) or surrender post-buckling (slab) can also continue bearing load after the interior fill plate flexing of steel plate shear force wall; Even under the situation that interior fill plate is torn; Its performance degradation is also not obvious, has that initial lateral rigidity is big, the hysteresis stable performance, energy dissipation capability is good, ductility is big, resist advantages such as deformability under the cyclic loading is strong.
(2) it is thinner to fill out steel plate in the steel plate shear force wall, and ratio of height to thickness can reach 250～500, can increase the effective usable floor area in house.
(3) for steel frame-steel concrete nuclear core-tube structure, change the steel plate shear force wall structure into, can significantly improve its rigidity and ductility like the core tube; Realize coupling with outside framework material, ductility, rigidity; Reach dual purpose of setting up defences, because it is compared from heavy and light with reinforced concrete shear wall, geological process is little simultaneously; Thereby the vertical and horizontal loading that is delivered on the basis reduces, and has reduced foundation cost.
(4) the steel plate shear force wall construction is simple, and construction speed is fast.Traditional steel frame-steel plate shear force wall structural requirement node is and rigidly connects, and this just needs at the scene welding in a large number, and workload is big, speed of application is slow and quality is not easy, and has also increased steel using amount and construction cost.
Summary of the invention
The purpose of the utility model is, a kind of semirigid frame-steel plate shear force wall structure is provided.
In order to realize above-mentioned task, the utility model is taked following technical solution:
A kind of semirigid frame-steel plate shear force wall structure is made up of frame column, Vierendeel girder, otic placode and steel plate shear force wall, it is characterized in that, and the semi-rigid framework that connects to form of described frame column and Vierendeel girder, steel plate shear force wall is connected in the framework through otic placode.
Other characteristics of the utility model are: among described steel plate shear force wall can adopt does not has the steel plate wall of putting more energy into, cross the is put more energy into steel plate wall or the steel plate wall of tiltedly putting more energy into any.
The semirigid frame of the utility model-steel plate shear force wall structure, anti-seismic performance is good, can save steel using amount, reduces the field Welding workload, promotes speed of application.In many high-rise steel structure buildings, have broad application prospects.
Description of drawings
Fig. 1 is that steel plate shear force wall is not have the semirigid frame-steel plate shear force wall structural representation of putting more energy into.
Fig. 2 is that steel plate shear force wall is semirigid frame-steel plate shear force wall structural representation that cross is put more energy into.
Fig. 3 is that steel plate shear force wall is the semirigid frame-steel plate shear force wall structural representation of tiltedly putting more energy into.
Label is represented respectively among the figure: 1, frame column, 2, Vierendeel girder, 3, otic placode, 4, steel plate shear force wall, 5, the cross stiffening rib, 6, oblique stiffening rib.
Below in conjunction with accompanying drawing the utility model is done further to specify.
The specific embodiment
Referring to Fig. 1; The semirigid frame of the utility model-steel plate shear force wall structure; Constitute by Vierendeel girder 1, frame column 2, otic placode 3 and steel plate shear force wall 4; Frame column 1 and Vierendeel girder 2 are through the semi-rigid framework that connects to form, and otic placode 3 is positioned at around the framework, and steel plate shear force wall 4 is connected in the framework through otic placode 3.
When being connected in steel plate shear force wall 4, cross stiffening rib 5 forms steel plate shear wall with cross stiffeners; Its structure chart is seen shown in Figure 2.
When being connected in steel plate shear force wall 4, oblique stiffening rib 6 forms oblique stiffened steel plate shear wall; Its structure chart is seen shown in Figure 3.
Adopt the semirigid frame-steel plate shear force wall structure of the utility model; In the concept phase; The cross section of frame column 1 and Vierendeel girder 2 confirmed by vertical load, and the thickness of steel plate shear force wall 4 and the mode of putting more energy into (nothing is put more energy into, cross is put more energy into, tiltedly put more energy into) are confirmed by horizontal loading.In the construction documents design phase, be optimized design through finite element analysis.The otic placode 3 that connects steel plate shear force wall 4 usefulness is connected on frame column 1 and the Vierendeel girder 2 in factory, and after frame column 1 installed with Vierendeel girder 2 at the construction field (site), steel plate shear force wall 4 was connected with otic placode 3 through the form of bolt or welding.
