Description
Technical field
The invention belongs to field of civil engineering, relate to a kind of buckling restrained brace for reducing engineering structures seismic response.
Background technology
Buckling restrained brace is a kind of novel lateral resistant member, is also a kind of energy-dissipating and shock-absorbing member that utilizes metal yield dissipation seismic energy simultaneously, has common support and metal damper dual-use function concurrently.Under little shake effect, the various piece of buckling restrained brace all keeps elasticity, jointly forms overall Lateral Resistant System with agent structure, guarantees that the sidesway of structure meets the demands.Under middle shake or large shake effect; the partial cross section of buckling restrained brace core board can enter surrender under axial tension or pressure-acting; form core board surrender section; utilize the metal yield of core board surrender section most of earthquake energy that dissipates; thereby the vibration of the agent structure that greatly decays reaction, reaches the target of protecting agent structure.Because it has stable performance, the advantage such as easy to make, with low cost, be widely used in recent years.
At present, the cover pipe concrete buckling restrained brace being widely studied and applied is mainly made up of following three parts: bear the core energy dissipation component of axial load, prevent core component produce the lateral restraint parts of entirety or cripling and reduce frictional resistance without binding material.The compound section form that wherein core component mostly is an in-line steel plate or is formed by polylith in-line steel plate, lateral restraint parts are to be formed by fill concrete in steel pipe or mortar piece, avoid directly contacting with screed without binding material parcel core component.The buckling restrained brace of this kind of form is done the used time in axial compression, core component can produce very large extruding force to the concrete being in contact with it or screed, test shows to cause the part of concrete or screed to crush, thereby cause that core component cripling is excessive, and then have a strong impact on the performance of buckling restrained brace.
Summary of the invention
The present invention is all directly born by concrete or mortar the extruding force of constraint component in order to solve traditional sleeve concrete buckling restrained brace core component under reciprocating load, concrete or mortar are crushed and cause the cripling of core component excessive and lost efficacy, and then have proposed put more energy into parts and concrete or mortar of a kind of utilization and combine to retrain the cover pipe concrete buckling restrained brace of putting more energy into of core component.
The technical solution used in the present invention is: the one cover pipe concrete buckling restrained brace of putting more energy into, comprises core component, without binding material, the parts peace treaty bundle parts of putting more energy into;
Described constraint component is arranged on core component periphery, and constraint component is made up of sleeve pipe fill concrete or mortar; The described surface that is wrapped in core component without binding material;
Described without having additional the parts of putting more energy on binding material external surface, the put more energy into flat side of parts or edge of a wing lateral surface is close to being enclosed with without the core component external surface of binding material along core component length direction, the length of parts of putting more energy into is greater than core board surrender segment length, is positioned in constraint component together with the parts of putting more energy into without binding material.
As preferably, the casing profile of described constraint component is square, rectangle, polygon or circle.
As preferably, the cross section of described core component is in-line, cross, T font or I-shaped.
As preferably, described in put more energy into parts for dull and stereotyped, sheet width is in-line core component width or T font and I-shaped flange width 0.5～1 times.
As preferably, described in the parts of putting more energy into be channel, one side of channel or both sides or three limits are close to without binding material surface with parcel core component.
As preferably, described in the parts of putting more energy into be L shaped, a limb of L shaped or two limbs are close to without binding material surface with parcel core component.
As preferably, described in the parts of putting more energy into be rectangular tube, one side of rectangular tube or both sides or three limits are close to without binding material surface with parcel core component.
As preferably, described in the parts of putting more energy into be flap, limit, the described flap edge of a wing is close to without binding material surface with parcel core component.
As preferably, described in put more energy into offer hole on parts or dorsad without binding material side weld stud, to stop the relative slippage of putting more energy between parts and concrete or mortar piece.
Supporting member of the present invention is set up the parts of putting more energy into parcel core component without binding material layer surface, then the sleeve pipe that is filled together concrete or mortar retrains, these parts of putting more energy into can be in-line steel plate, channel, L shaped, rectangular tube, flap or its combining form conventionally, and form the novel sleeve pipe buckling restrained brace of putting more energy into.This novel buckling-restrained bracing member is by the parts of putting more energy into, the extruding force that core board is transmitted is evenly delivered on more large-area concrete or mortar chunk facing by the parts of putting more energy in whole or in part, the put more energy into flat side of parts or the width of edge of a wing lateral surface is about 0.3～1 times that is enclosed with without the corresponding face width of the core component of binding material, can change the compressive stress bang path of concrete or mortar and core component contact surface, thereby effectively avoid concrete or mortar buckling restrained brace performance crushed and that cause to reduce.In addition, by setting up the parts of putting more energy into, the contact surface form of core component and constraint component is contacted and changed into steel and contact with the mixing of Steel concrete or mortar surface layer with steel by original Steel concrete or mortar surface layer, the coefficient of contact friction of invar and steel is lower than the coefficient of contact friction of Steel concrete or mortar surface layer, so can reduce the friction between core component and constraint component, thereby effectively improve the performance of buckling restrained brace.
The present invention has following beneficial effect:
1. the present invention sets up the parts of putting more energy between the core component of traditional buckling restrained brace and constraint component, the extruding force to constraint component that core component can be produced when the pressurized is some or all of by putting more energy into parts Transmit evenly on larger area concrete or mortar chunk facing, the put more energy into flat side of parts or the width of edge of a wing lateral surface is about 0.3～1 times without the corresponding face width of the core component that has binding material of parcel, can change the local compressive stress bang path on concrete or mortar piece surface, thereby having avoided common is crushed by part and the inefficacy of the buckling-restrained bracing member that causes by concrete or mortar piece, make the performance of buckling restrained brace be able to more fully effectively performance.
2. the present invention is by the parts of putting more energy into of setting up between the core component at traditional buckling restrained brace and constraint component, to contact and change into steel and contact with the mixing of Steel concrete or mortar surface layer with steel by original Steel concrete or mortar surface layer with the contact surface form of buckling-restrained bracing member core component, can effectively reduce the frictional force between contact surface, be conducive to improve the overall performance of buckling restrained brace.
