Abstract
The utility model belongs to building engineering structure shock proof technology, in particular relating to a mild steel damper construction. The utility model is characterized in that a horizontal joint steel plate is embedded in a building structural framing beam, the mild steel damper is welded at the embedded horizontal joint steel plate by multi-pass welding, the other end of the mild steel damper is welded at a lower horizontal joint steel plate, the plane of the mild steel damper is parallel to the plane of the structural framing thereof. The utility model has the advantages of greatly improving the initial rigidity of the mild steel damper to provide enough initial rigidity under micro-earthquake action and dissipate seismic energy under macro-earthquake action. The utility model saves steel products and has specific economic profit.
Description
Technical field
The utility model belongs to building engineering structure anti-seismic technology field, relates to a kind of structure of mild steel damper.
Background technology
The energy-dissipating and shock-absorbing structure has obtained extensive studies and use since introducing engineering circle, and energy-dissipating and shock-absorbing has obtained using widely since introducing civil engineering field as a kind of Passive Control mode.Its cardinal principle is by specific additional dissipative cell is set in structure, and the energy that earthquake motion is inputed to structure is guided dissipative cell into, thereby absorbs most of earthquake motion input energy, alleviates damage of structure.Developed multiple dissipative cell at present both at home and abroad, wherein mild steel class damper is widely promoted practicality with its economic, practical property at building circle.Mild steel class damper mainly is by providing good plastic strain to realize energy-dissipating property after the steel surrender, damper adopted damper plane and structural plan to be arranged vertically mode in order to improve its energy dissipation capacity in the past, therefore the initial stiffness of mild steel class damper is less relatively, can only embody its single energy-dissipating property.
And in fact steel not only have good plasticity hysteretic energy performance, not having certain initial stiffness before the surrender, how to make full use of the initial stiffness of steel, and bring into play the dual significant of plasticity power consumption in its surrender back.
Summary of the invention
The purpose of this utility model provides a kind of structure of soft firm damper, by the damper steel plate is arranged in parallel in framework, solves the not enough problem of damper initial stiffness.
The technical solution of the utility model is as follows:
A pre-buried level connects steel plate in building structure pre-sets the Vierendeel girder of damper, be welded on pre-buried level and connect on the steel plate mild steel class damper is stacked, another section of mild steel damper level that is welded on down connects on the steel plate mild steel class damper plane and place structural framing plane parallel.
Effect of the present utility model and benefit are mainly reflected in mild steel class damper by being parallel to the layout mode, increased substantially the initial stiffness of mild steel class damper, also can guarantee simultaneously the energy-dissipating property after steel is surrendered, can realize providing enough initial stiffnesses under the little shake effect antidetonation thought of dissipation seismic energy under the big shake effect.Save the steel using amount of mild steel damper, had good economic benefit.
Description of drawings
Accompanying drawing 1 is that a kind of mild steel damper is constructed positive elevational schematic view.
Among the figure: 1 structural frames is set a roof beam in place; 2 frame columns; 3 steel support; 4 upper end levels connect steel plate; 5 mild steel dampers; 6 lower end levels connect steel plate.
Accompanying drawing 2 is mild steel damper A-A generalized sections.
Among the figure: 1 structural frames is set a roof beam in place; 3 steel support; 4 upper end levels connect steel plate; 5 mild steel dampers; 6 lower end levels connect steel plate.
The specific embodiment
Be described in detail most preferred embodiment of the present utility model below in conjunction with technical scheme and accompanying drawing.
During concrete enforcement, at first pre-buried upper end level in the Vierendeel girder 1 is connected steel plate 4, with mild steel damper 5 stacked placements, and level connects on the steel plate 4 on being welded in; Mild steel damper 5 other ends are welded on the lower end level and connect on the steel plate 6.The lower end level connects steel plate 6 and is connected to frame column 2 bottoms by steel support 3, and guarantee that the steel plate plane is parallel with frame plane this moment.
