The steel plate-steel support combined lateral force resisting member comprises a steel plate, a steel support integrally connected with the steel plate, wherein the steel plate is in a shape like a Chinese character 'tu', the steel support comprises two portions respectively arranged on two sides of the steel plate, bolt holes are arranged on the steel support at intervals, bolt holes are also arranged at corresponding positions of the steel plate, the two portions of the steel support are respectively connected with the steel plates through high-strength bolts, the steel support is arranged in a V-shaped mode and used for providing a part of axial tension resisting and compression resisting capacity of the lateral force resisting member. The main purpose is that the steel support is utilized to constrain deformation outside a plane of the steel plate so as to avoid 'pinch' effect of a hysteretic curve, a pulling force field of the steel plate is utilized to constrain a phenomenon that an extreme point of the compressed steel support in a structural plane is often unstable, and accordingly the lateral force resisting member with excellent anti-seismic property is obtained.

Description

Steel plate-steel support combines lateral resistant member and applies the post and beam structure of this component

Technical field

The present invention relates to a kind of lateral resistant member and apply the post and beam structure of this component, more particularly, relate to a kind of steel plate-steel support combination lateral resistant member and apply the post and beam structure of this component.

Background technology

Earthquake is the maximum natural enemy of building, is grave danger of human survival.Dual seismic system in steel work, often adopts steel plate shear force wall or bracing members as first anti-vibration defense lines, resists the horizontal force of little shake, middle shake.Under large shake effect, steel plate shear force wall or bracing members are consumed seismic energy by the flexing of self with surrender, play the effect of " fuse " on the one hand, and the safety of the steel frame of gravity load is born in protection; On the one hand because the degeneration of stiffness by itself reduces earthquake response; the steel frame as second anti-vibration defense lines is enable to resist the geological process reduced; thus guarantee that agent structure is not collapsed under large shake effect, the safety of protection lives and properties, is suitable as the form of structure of earthquake zone highrise building.

But conventional thin steel plate shear wall, because the outer rigidity of its steel plain is very little, shear buckling will occur at little horizontal loads lower steel plate, the diagonally opposing corner pulling force field formed after need utilizing steel plate flexing is to resist horizontal force (pulling force field is by carrying out anchoring with the connection of framework).Because steel sheet can not pressurized, thus steel plate is obviously reduced in tensile stress-compressive stress transformation stage supporting capacity, there is " pinching " phenomenon of the hysteresis loop under reciprocating load, this makes the plasticity hysteretic energy ability of steel be not fully utilized, and have impact on the further raising of anti-seismic performance.And steel plate is under horizontal reciprocating load action, buckling direction and pulling force field, diagonal angle be alternately change constantly, and can send loud, similar noise of beating a drum, this creates very important negative effect to the normal use of structure.

Conventional center support Lateral Resistant System, due to most of supporting capacity can be lost because of unstability when pressurized is supported on and is subject to larger load, thus the ductility of structure is reduced greatly, hysteresis loop under reciprocating load is full not, malformation ability, energy dissipation capacity is more weak, and Braced Frames structure is when horizontal loading is larger, (the such as V-arrangement when knighthead intersects at Vierendeel girder, timbering with rafter arch sets), there will be pressurized supports because unstability supporting capacity reduces the situation that cannot balance the vertical force component that tension supports greatly, now " Anti-quake Architectural Structure Design specification " GB50017-2010 specifies need the Vierendeel girder be connected with support be designed enough powerful, this makes beam section obviously increase, " strong column and weak beam " principle that design aspect specifies according to GB50017-2010 simultaneously must be strengthened the post that Vierendeel girder is connected therewith again, so not only the steel using amount of structure increases greatly, and the rigidity of structure can obviously increase, thus cause larger earthquake response.

Through patent retrieval, China Patent No. application number: 200810240517.2, publication date is: on June 17th, 2009, invention and created name is: steel-truss-steel-plate combination shear wall and preparation method thereof.This application case discloses a kind of shear wall, in particular to steel-truss-steel-plate combination shear wall and preparation method thereof, comprise frame beam, and the frame columns of frame beam consolidation and the steel plate be arranged between frame beam and frame columns, frame beam comprises section steel beam and the concrete be cast in outside section steel beam forms shape steel-concrete combined beam, frame columns is by shaped steel and is cast in the profile steel concrete column that the concrete outside shaped steel forms, section steel beam in shaped steel in profile steel concrete column and steel plate and frame beam is connected, oblique consolidation shaped steel bearing diagonal on steel plain, shaped steel bearing diagonal can be herringbone, X-shaped or splayed are arranged.Section steel beam, profile steel concrete column, shaped steel bearing diagonal and steel plate combination, form steel truss-armor Plate.The shear wall of this application case is larger than the initial stiffness of existing shear wall, supporting capacity is high, but its weak point is: the steel plate side that is supported on of this application case is arranged, asymmetric to the girder steel longitudinal axis, thus, when supporting stressed, girder steel is subject to obvious twisting action by due to support to the bias of the girder steel longitudinal axis; Again because the anti-torsion ability of i shaped cross section beam is very weak, so serious torsional deflection or unstable phenomenon may be there is due to support to the torsional interaction of girder steel bias generation in beam.

And for example China Patent No. application number: 200910090731.9, publication date is: on March 17th, 2010, invention and created name is: the flexing suppressive shear wall that put more energy into shaped steel and embedded steel plate can slide.This application case discloses the flexing suppressive shear wall that a kind of put more energy into shaped steel and embedded steel plate can slide, and shear wall is made up of embedded steel plate, formed steel reinforcing rib, splice bar and edge member; Embedded steel plate adopts the steel sheet of high ductility steel rolling; Edge member is made up of edge posts and edge girder; Formed steel reinforcing rib adopts the shaped steel of I-shaped, box-shaped, C shape, L shape, crimping hat or other section form; Embedded steel plate opens quarter circular arc breach at corner place; Embedded steel plate is connected by splice bar with edge member; By penetrating both high strength exploitation between embedded steel plate and formed steel reinforcing rib.What this application case provided put more energy into shaped steel and the flexing suppressive shear wall that embedded steel plate can slide can be used as the novel lateral resistant member of high-rise building steel structure or other structure, but its weak point is: the shaped steel in this application case only plays tectonism, for suppressing the flexing of embedded steel plate, shaped steel itself is not lateral resistant member, and its mechanical property can not be fully used.

Summary of the invention

the technical problem that invention will solve
