A separate anti-buckling brace connected by wavy webs

A technology of anti-buckling bracing and wavy web, which is applied in earthquake-proof, building components, etc., can solve the problems of reducing bearing capacity, material waste, and limiting the extent of expansion of core sections, so as to reduce the amount of steel used and reduce the amount of steel used for webs. the effect of increasing the shear buckling load

Problems solved by technology

However, in order to prevent the occurrence of local buckling of the plate, it is necessary to take a larger value for the thickness of the flat web connecting the two limbs, or to reduce the height of the web; this will inevitably result in waste of materials, or limit the expansion of the inner core section degree, reduce the bearing capacity

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 [0001] The invention relates to a separate anti-buckling support connected by a wave web, belonging to the technical field of structural engineering. Background technique [0002] Buckling-resistant braces, as a new type of lateral force-resisting members, first appeared in the 1970s. The anti-buckling bracing is composed of inner core members and peripheral restraint members. Under the action of small earthquakes, the inner core members of the anti-buckling bracing members remain elastic and are used as lateral force members of the main structure; under the action of moderate and large earthquakes, the buckling-resistant bracing The inner core component first enters into yield, which protects the main frame, and consumes a large amount of seismic input energy at the same time, and has a very full hysteresis curve. It is precisely because of its two functions of "support" and "energy dissipation", that it is one of the best energy dissipation and shock absor...
