Abstract
The invention relates to a separate buckling restrained brace using corrugated webs for connection, and belongs to the field of structural engineering. Two linear core steel plates are disposed separately, each linear core steel plate is coated with a peripheral member, and hard rubber is stuck to the surfaces of the areas coated with the restrained members. Each restrained member is formed by pouring concrete inside a peripheral rectangular steel tube. Long edges of the two restrained members are placed in parallel. The two corrugated webs are disposed between the restrained members in parallel, and connected with the same by welding. The separate buckling restrained brace using the corrugated webs for connection adopts a branch section to enable core sections to expand fully, and raw materials are saved greatly. The corrugated webs are used for connecting two branches of the member, and by the aid of the characteristic that the corrugated webs are high in out-of-plane bending rigidity, the webs can be made to be high but thin. Due to the arrangement of the two corrugated webs and end cover plates, the internal structure of the buckling restrained bracing member is not exposed, and durability and corrosion resistance of the member are enhanced.
Description
Technical field
The present invention relates to a kind of anti-buckling support of separate type connecting with wave webs, belong to technical field of structural engineering.
Background technology
Anti-buckling support, as the novel lateral resistant member of a class, comes across 20 century 70s the earliest.Anti-buckling support is comprised of inner core component and peripheral constraint component, and under little shake effect, the inner core component of curvature-prevention support component keeps elasticity, as the lateral resistant member of agent structure, uses; Under middle shake and large shake effect, the inner core component rate of anti-buckling support is introduced into surrender, plays the effect of protection main body frame, consumes a large amount of inputting seismic energies simultaneously, has very full hysteresis loop.The function that has " support " and " power consumption " two aspects concurrently just because of it, makes it as one of best energy-dissipating and shock-absorbing member, is widely used gradually in the middle of the high building structure with China, especially at Japanese slope celestially after the north ridge earthquake of the Zhen He U.S..
Tradition curvature-prevention support component generally adopts global sections form, yet, when the desired tonnage of anti-buckling support is larger, will cause kernel and member integrated cross section excessive, from great and waste material.For this problem, the anti-buckling support of a kind of separate type has been proposed in recent years, inner core component separate layout is formed to two minutes limbs of member, utilize plain plate to connect two minutes limbs, can make interior nuclear cross section fully launch, obtain larger bending rigidity.But in order to prevent the generation of Plate local buckling, the flat web thickness that connects two minutes limbs need to be got to larger value, or reduce the height of web; This certainly will cause the waste of material, or the degree that in restriction, nuclear cross section launches, and reduce bearing capacity.
Summary of the invention
The anti-buckling support of the separate type connecting with wave webs that the present invention proposes adopts separate type cross section, and interior nuclear cross section is fully launched, and significantly saves raw material, has especially made up the anti-buckling deficiency being supported in large-tonnage member designs in monolithic cross section; Use two minutes limbs of wave webs connecting elements, utilize the outer large feature of bending rigidity of wave webs face, web can be done to get Gao and thin, when effectively reducing web steel using amount, improve the shearing resistance Buckling Loads of web, be more prone to meet the rigidity requirement in component conveying and installation process; By the setting of two wave webs and closing panel, curvature-prevention support component internal structure is not exposed, time more attractive in appearance, the durability of lifting member and corrosion resistance.
A kind of anti-buckling support of separate type connecting with wave webs, it is characterized in that, described anti-buckling support is by forming with lower member: two in-line kernel steel plate, two confining parts, vulcanie, two closing panels, connect floor, two wave webs; Described confining part is by forming at the inner fluid concrete of peripheral square tube.
Described two in-line kernel steel plate adopt separate layout, are wrapped up respectively by a confining part, in the area surfaces of its restrained member parcel, paste vulcanie; In-line kernel steel plate length is greater than the length of confining part, and kernel steel plate has overhanging section.
Totally two of described confining parts, measure-alike; Two long parallel placements in limit of confining part; Described two wave webs are parallel to each other and are placed between confining part, by welding, are connected with two confining parts.
Totally two of described closing panels, measure-alike, be rectangular flat, above with two rectangular openings; Described rectangular opening shape is identical with in-line kernel steel plate cross section; Two closing panels are placed in curvature-prevention support component two ends, and in-line kernel steel plate is passed from rectangular opening; The end cross-sectional of closing panel surrounding and confining part and wave webs is by being welded to connect.
Described connection floor is rectangle plain plate, and its length equates with the overhanging intersegmental distance of two in-line kernel steel plate; Connecting floor adopts twin fillet wolt to be connected with overhanging section of kernel one word steel plate; Connect between floor and closing panel and have certain spacing, spacing size is determined according to connecting floor deformation limit value under axial pressure effect.
Described connection floor is connected with structural framing with hinged or the form that rigidly connects; Described being articulated and connected, by open single pin hole on connection floor, and is connected realization with the otic placode being fixed on described structural framing by bearing pin; Describedly rigidly connect connection, by opening bolt hole connecting on floor, and by high-strength bolt, be connected realization with the cover plate being fixed on described structural framing.
The present invention proposes a kind of novel anti-buckling support connecting with wave webs, have the following advantages:
(1) adopt a minute limb formula cross section, interior nuclear cross section is fully launched, significantly save raw material, especially made up the anti-buckling deficiency being supported in large-tonnage member designs in monolithic cross section;
(2) use two minutes limbs of wave webs connecting elements, utilize the outer large feature of bending rigidity of wave webs face, avoided flat web to be easy to occur the problem of cripling, wave webs can be done to get Gao and thin, when effectively reducing web steel using amount, improve the shearing resistance Buckling Loads of web, be more prone to meet the rigidity requirement in component conveying and installation process;
(3) by the setting of two wave webs and closing panel, curvature-prevention support component internal structure is not exposed, time more attractive in appearance, the durability of lifting member and corrosion resistance.
