Description
Technical field
The present invention relates to a kind of Wasted-energy steel plate wall of building structure, particularly relate to a kind of anti-flexing perforate Wasted-energy steel plate wall of partition type of building structure.
Background technology
Earthquake disaster has sudden and crushing, and the safety of human life, property in serious threat.Annual failure earthquake is nearly thousand times in the world, and a violent earthquake can cause the economic loss of more than one hundred billion dollar, causes the hundreds of thousands people dead or serious wounded or disabled.China is located in the world on two most active earthquake zones, is one of the most serious country that suffers disaster from an earthquake, and the casualties that earthquake causes occupies first place in the world, and economic loss is also very huge.In the earthquake considerable damage of building with collapse, be the immediate cause that causes earthquake disaster.When earthquake occured, ground vibration caused the earthquake response of structure.Be fixed in the building structure on ground for the basis, its reaction is along successively amplifying highly from top to bottom.Because the earthquake response (acceleration, speed or displacement) of works a part is excessive, makes the heavy damage of main body load-carrying members even collapse; Although or agent structure do not destroy, the breaking-up such as architectural coating, finishing or other non-structure accessory and cause heavy losses; Or indoor expensive instrument, damage of facilities cause serious loss or secondary disaster.For fear of the generation of above-mentioned disaster, people must control the earthquake response of structural system, and eliminate " amplifier " effect of structural system.
Steel plate shear wall structure is a kind of novel lateral resisting structure system that 20 century 70s grow up.Steel plate shear force wall is made of embedded steel plate, vertical edges member (post) and horizontal edge member (beam), its holistic resistant behavior is similar to the vertical semi girder of bottom build-in, wherein the vertical edges member is equivalent to flange of beam, embedded steel plate is equivalent to web, and the horizontal edge member can Approximate Equivalent be transverse stiffener then.Embedded steel plate can adopt without stiffening rib and the structural form that stiffening rib is arranged.Under severe earthquake action, can take full advantage of the Post-Bucking Strength of steel plate without the steel plate shear force wall of putting more energy into, and have good ductility and energy dissipation capacity.The steel plate shear force wall of putting more energy into then can limit flexing outside the plane of steel plate, thereby improves the flexing bearing capacity of structure, helps to strengthen lateral deformation stiffness and the convenient construction of structure under wind and little shake effect.Add concrete shear wall structure system with traditional steel frame or steel frame and compare, steel plate shear wall structure has thin thickness, from heavy and light, the advantage such as construction speed is fast and ductility is good.Existing achievement in research and case history show, steel plate shear force wall is a kind of Lateral Resistant System that has very much development potentiality, is particularly useful for high-intensity earthquake set up defences highrise building and the seismic hardening in district.In the past few decades, the various countries scholar has carried out the research of many tests and theoretical side to this structure.These researchs have all obtained common conclusion: this structural elasticity initial stiffness is high, displacement ductility is large, Hysteresis Behavior is stable.
China starts late about the research of steel plate shear force wall, " Technical Specification for Steel Structure of Tall Buildings " appendix four is about the calculating of steel plate wall, think only Under Lateral Loading of steel plate wall structure, with the design limit state of shearing elasticity buckling strength as steel plate wall, there is not consideration in the problem of axial load effect lower steel plate wall flexing.Particularly some Wasted-energy steel plate walls easily produce flexing at present, also have the plasticity distribution of some Wasted-energy steel plate walls more concentrated, are unfavorable for power consumption, all need to be solved preferably.
Summary of the invention
The present invention is directed to the technical problem of above-mentioned existence; provide a kind of power consumption effect that utilizes partition type to prevent flexing perforate Wasted-energy steel plate wall can reduce the earthquake response of building structure; building structure is played a very good protection; and establish the hole in adopting and can effectively solve plasticity distribution concentration problem, improve the anti-flexing perforate Wasted-energy steel plate wall of partition type of the energy dissipation capacity of structure.
The technical scheme of technical solution problem of the present invention is to achieve these goals:
Partition type is prevented flexing perforate Wasted-energy steel plate wall, comprising: in fill out steel plate, steel plate stiffening rib and steel column and girder steel, in fill out steel plate and be fixed in steel column and the girder steel by angle steel, bolt, fill out in it and be cross in steel plate the steel plate stiffening rib is set; Fill out steel plate in inciting somebody to action and be evenly divided into four rectangular areas; Each zone all is divided into two Delta Regions by diagonal wherein, be made as in the diagonal in the non-layout and establish bore region, establish the hole in establishing in other zone, and rectangular Triangle-Profile, in fill out in the whole zone of steel plate, be made as in the non-layout in two diagonal and establish bore region, establish the hole vertical non-alignment in two Delta Regions, the quantity of every vertical round equates.
Establish the hole in described for oval, the major axis of establishing the hole in described is that vertical direction is arranged.
Described steel plate stiffening rib is filled out on the steel plate in being fixed on by bolt, nut and billet.
Described steel column and girder steel and in to fill out steel plate with bolts.
The present invention compared with prior art has following advantages and effect:
Formula anti-flexing perforate Wasted-energy steel plate wall in district of the present invention has larger vertical rigidity and horizontal rigidity, improved the anti-seismic performance of steel plate shear force wall, realized that steel plate shear force wall and energy consumer unite two into one, and can be widely used in the energy-dissipating and shock-absorbing of steel work and reinforced concrete structure.It has a series of superior characteristics such as high, the anti-side rigidity of supporting capacity is large under the geological process, energy dissipation capacity is strong.
