Description
Technical field
The utility model relates to a kind of novel energy-consumption, the anti-buckling steel plate shear force wall that oblique notches, and belongs to technical field of structural engineering.
Background technology
In seismic design, how to alleviate the damage (as moulding distortion) of building structure in earthquake (comprising main bearing member, non-structural element) irrecoverability, making structure after earthquake, can repair rapidly and can normally use, is the focus of current earthquake resistant engineering research.The introducing of dissipative member is a kind of very effective method, and can effectively the dissipate input energy of earthquake of dissipative member is set in structure, and the distortion of structure is mainly concentrated in dissipative member, avoids other members in structure to destroy.
Steel plate shear force wall is the good structural element of a kind of anti-seismic performance, and in China's super highrise building, has started in recent years application, but has mainly considered the lateral resistant ability of steel plate shear force wall at present, and considers its power consumption contribution not yet in effectly.
The non-thin steel plate shear wall of putting more energy into is done the used time in horizontal shear, and flexing very easily occurs steel plate, finally with the form of pull strap, bears external load; When load reversal does the used time, the pull strap producing under previous step load action is deactivated, and forms gradually reversal interlocking relay band; In this process, steel plate constantly changes in complicated applied force state and steel plate flexing, when steel enter surrender, while producing inelastic buckling, in steel plate, just form the face that cannot recover and be out of shape outward, and then form fold, at fold place, steel are very easily torn or rupture, therefore, the non-anti-fatigue performance of thin steel plate shear wall under reciprocating load of putting more energy into is not enough.
Employing is in the measure of steel plate both sides oversite concrete plate, the face that can retrain steel plate is out of shape outward, delay steel plate flexing, by improving the contracting of pinching of hysteresis loop that steel sheet causes because flexing causes pull strap constantly to occur to transform, solve the problem that steel plate energy dissipation capacity can not be not fully exerted.But the steel plate in shear wall is in complicated applied force state, the failure mode of more difficult control shear wall, thereby cannot accurately judge its yield load and yield displacement, be not easy to realize the controlled design of parameter (yield displacement, yield force); Simultaneously in current engineering application, steel plate mostly is a monoblock steel plate, when the size of edge frame and one timing of the yield strength of steel, the strength and stiffness of steel plate are only relevant to the thickness of steel plate, project planner is difficult to only by adjusting the thickness of steel plate, obtain the Rigidity and strength that design needs, when steel plate shear force wall is applied to multi-rise building, often because design thickness is too thin, cannot meet the thickness that processing request increases steel plate, cause the waste of steel, therefore greatly limited steel plate shear force wall applying in multi-rise building.
Utility model content
The purpose of this utility model is to provide a kind of and is widely used, energy-dissipating property is remarkable, the controlled anti-buckling steel plate energy-consuming shear wall that oblique notches of design parameters.
The utility model solves the technical scheme that its technical problem adopts:
The anti-buckling steel plate energy-consuming shear wall that oblique notches the utility model proposes, is characterized in that, described shear wall mainly by the steel plate that oblique notches, be arranged on steel plate both sides and retrain the concrete slab of the outer distortion of steel plate surface, the edge frame being connected with steel plate forms; On the described steel plate that oblique notches, according to actual conditions and design, need to offer multi-form skewed slot, surrounding is bolted and is embedded in edge frame; Shown in edge frame by left hand edge frame column, top edge Vierendeel girder, right hand edge frame column and lower limb Vierendeel girder, jointly formed.
Above-mentioned anti-buckling oblique notching in steel plate energy-consuming shear wall, described both sides concrete slab connects by penetrating the bolt of three blocks of plates, for reducing the impact of bolt hole on steel plate between skewed slot, guarantee the desirable tension and compression deformation of steel plate between groove simultaneously, bolt hole is arranged in skewed slot; Described concrete slab is determined concrete thickness according to steel plate thickness and the outer anti-side rigidity of required face thereof, and adopts double-layer double-direction arrangement of reinforcement, describedly two-wayly for offering direction along skewed slot, offers direction with vertical skewed slot.
Above-mentioned anti-buckling oblique notching in steel plate energy-consuming shear wall, for preventing that the friction between steel plate and concrete slab from causing concrete slab to ftracture too early, non-cohesive material or certain gap are set between steel plate and both sides concrete slab, its gap arranges because meeting the low order flexing that concrete slab still can operative constraint steel plate, and general value is not more than 1mm.
Above-mentioned anti-buckling oblique notching in steel plate energy-consuming shear wall, described concrete slab only works to retrain the steel plate that oblique notches, between its edge frame being connected with the steel plate that oblique notches, leave certain gap, its value size is made used time concrete not because contact the maximum conditions setting that participates in opposing horizontal loads with edge frame according to assurance structure in large shake.
Above-mentioned anti-buckling oblique notching in steel plate energy-consuming shear wall, for ease of realizing the quick reparation after industrialization and shake, the described steel plate surrounding of oblique notching is inserted and is designed in advance in the symmetrical angle steel on edge frame, and be attached thereto by bolt, described symmetrical angle steel has been strengthened the steel plate weak part forming without concrete slab constraint because of edge simultaneously.
Above-mentioned anti-buckling oblique notching in steel plate energy-consuming shear wall, by offer skewed slot on steel plate, by the weak part of steel plate from edge transitions to inside, form the described steel plate that oblique notches, changed the stress of steel plate complexity, it is the main force mode that is subject to that steel plate tension and compression deformation between groove is take in formation, is not only conducive to realize stable tension and compression power consumption; Can, by investigating the tension and compression deformation of steel plate between groove, determine preferably yield load and the yield displacement of shear wall simultaneously.
Above-mentioned anti-buckling oblique notching in steel plate energy-consuming shear wall, by changing the arrangement form of steel plate width, skewed slot between skewed slot width, groove, can design different shear wall strength and stiffness, and then realize different yield loads and corresponding yield displacement thereof, realize the controlled design of parameter.
Above-mentioned anti-buckling oblique notching in steel plate energy-consuming shear wall, the form of slotting on steel plate is divided into non-isometric skewed slot, single isometric skewed slot, arranges three kinds of isometric skewed slots more.
