Description
Technical field
The utility model belongs to building structure technology field, relates to a kind of dissipative cell and energy-consumption supporting member of building structure aseismatic mitigation, more particularly, relates to a kind of dissipative cell and prestressing force and exempts from energy consuming supporting member.
Background technology
For improving supporting capacity and the lateral rigidity of frame construction, increase structure building height, avoid strengthening too much beam cross-section and corresponding steel using amount, take frame construction as basis, along structure height, arrange that the formed framework-braced structures of support of some is a kind of cost-effective conventional lateral resisting structure system.Existing support mainly contains according to the common support of current Specification Design and anti-buckling support.There is following problem in these two kinds of supports: the easy pressurized flexing of common support, its tension and compression hysteresis significant reaction is asymmetric, Cyclic Loading during large shake very easily causes support itself and the inefficacy being connected or destruction, and the hysteretic energy ability variation after flexing, is difficult to effectively consume the energy of earthquake input; Anti-buckling support adopts bilinearity hysteretic behavior, and hysteresis loop is full, and energy dissipation capacity is strong, but after geological process, after especially large shake, there is very large permanent set in this support system, make to reinforce reparation more difficult, even cannot repair, caused economic loss and impact to use; In addition, if the maintenance impact building of building structure is used, can bring larger impact to public psychology, cause the public to throw doubt upon to the safety of building.
Framework-braced structures is under the horizontal reciprocating load actions such as earthquake or high wind, supporting member will bear tension and compression axial force repeatedly, but the conventional Compression Stability bearing capacity supporting is less than its tension bearing capacity conventionally, easy flexing during pressurized, after pressurized flexing, its supporting capacity reduces, Stiffness Deterioration, cause, in whole earthquake or disaster caused by a windstorm process, cannot providing stable energy dissipation capacity; Supporting member pressurized buckling failure, also by the maintenance cost increasing after calamity.For this reason, inventor congratulates to support the army etc. and has proposed unidirectional energy-consumption supporting member (ZL201320455039.3), unidirectional energy-consumption supporting member is paired reversed arrangement in each layer of structure, when earthquake or wind reciprocating make unidirectional energy-consumption supporting member pressurized, by the draw rod device vertical with support, make the axial compression that unidirectional energy-consumption supporting member bears greatly reduce or disappear, prevent unidirectional energy-consumption supporting member pressurized flexing, thereby reduce the maintenance cost after calamity.But only the supporting member of tension one side works, the supporting member of pressurized one side does not only play power consumption effect, and the most basic anti-side effect does not all have, and this has also caused the great wasting of resources.
Continuous progress along with engineering, and the development of material technology, the effect of prestressed cable in building structure is day by day familiar with and grasps by engineers and technicians, the rope material of prestressed cable also becomes more diverse, have wire rope cable body, steel strand cable body, steel tendon cable body and reinforcing pull rod cable body, with the structure of prestressed cable be applied in more and more large span public with industrial construction in.The exhibit halls of Shanghai New International Expo Center and Nanjing Railway Station waiting hall, all using prestressed draw-bar as wind bracing; Inventor Tang Bai mirror waits a kind of prestressed giant brace-frame structure (ZL20092023698.6) proposing, and has been applied to ordinary steel framework field using prestressed cable as lateral support.Research shows, will be greatly across prestressed cable as lateral support, prestressing force is that the flexible cable of oblique layout has been set up axial rigidity and stability, make the drag-line that pretension crosses both can bearing tension, also can bear pressure (as long as prestressing force is greater than the compressive stress that external loads causes), thereby support for structure provides elastic restraint, and without considering strut stability problem.Under earthquake and high wind effect, the internal force in prestressed cable brace shows as and increased by drag-line pulling force, and pressurized Suo Lali reduces, due to the high-strength characteristic of drag-line, although increased by drag-line pulling force, but still in elastic stage, pressurized Suo Ze pulling force reduces, especially in elastic stage.Therefore, must be pointed out, although prestressed cable can be used as lateral support, for structure provides anti-side rigidity, but it does not have the function of the energy of dissipation earthquake and disaster caused by a windstorm input building structure, this also just at present prestressed cable brace further break through and the bottleneck of extensive use.
Summary of the invention
The purpose of this utility model is defect and the technical problem of the function of the easy pressurized flexing of common rigid support that exists for above-mentioned prior art and the prestressed cable brace energy without dissipation earthquake and disaster caused by a windstorm input building structure, provides a kind of dissipative cell and prestressing force to exempt from energy consuming supporting member.
