Abstract
The invention provides a low waistband head steel shear plate damper without a rib. The low waistband head steel shear plate damper comprises a core steel plate, a left side flange plate, a right side flange plate, an upper flange plate and a lower flange plate. The core steel plate is connected with the left side flange plate and the right side flange plate through a penetration weld, the core steel plate is connected with the upper side flange plate and the lower side flange plate through a penetration weld, and upper side flange plate and the lower side flange plate are connected with the left side flange plate and the right side flange plate through a penetration weld. The low waistband head steel shear plate damper without the rib has many advantages that starting rigidity is large, small vibration deformation energy consumption is obvious, plastic deformation capacity is high a hysteretic curve is full and energy consumption capacity is good, thereby being an excellent energy consuming element.
Description
Technical field
The present invention relates to technical field of structural engineering, be specifically related to a kind of apleuria Low Yield Point Steel shear plate damper.
Background technology
As the dissipative cell of many Tall Frameworks, traditional hysteresis type damper has had good energy-dissipating property, but its energy consumption effect when small vibration is out of shape is not obvious, and its use in engineering is restricted.
In order to solve this shortcoming of traditional hysteresis type damper, present patent application has proposed a kind of novel hysteresis type damper, i.e. apleuria Low Yield Point Steel shear plate damper.By core steel plate is replaced by low yield point steel plate, its major advantage shows: (1), because Low Yield Point Steel is compared with common iron and had identical modulus of elasticity, poisson's ratio, the dissipative cell of therefore being made by described steel has larger initial stiffness equally.(2), because core board steel plate adopts Low Yield Point Steel, under smaller deformation condition, damper will enter surrender section, plastic strain occurs, dissipation effect energy structurally.(3) duty of apleuria Low Yield Point Steel shear plate damper in pure shear, stressed even, can bring into play fully to greatest extent its energy-dissipating property.Comprehensive above-mentioned advantage, apleuria Low Yield Point Steel shear plate damper is as the newcomer in dissipative cell, because its superior stress performance and energy-dissipating property can obtain application widely in many tall steel frames.
Summary of the invention
The object of the invention is for solving above-mentioned deficiency, a kind of apleuria Low Yield Point Steel shear plate damper is provided.
The object of the invention is to be achieved through the following technical solutions:
A kind of apleuria Low Yield Point Steel shear plate damper, comprise core steel plate, left side flap listrium, right side flap listrium, top flange plate and bottom wing listrium, core steel plate is connected by melt-through weld with left and right side frange plate, core steel plate is connected by melt-through weld with upper and lower frange plate, and left and right side frange plate is connected by melt-through weld with upper and lower frange plate.
The present invention also has some technical characterictics like this:
1. the core steel plate described in adopts the high ductility steel of low-yield, and strength classes of structural steel is selected Q100, Q160 or Q225.
2. the left and right side frange plate described in adopts common iron, the similar dumb-bell shape of shape.
3. the upper and lower frange plate described in adopts common iron, opens some bolts hole, does the use connecting.
The present invention has following useful effect:
The low steel shear plate of the low surrender of the apleuria damper that the present invention proposes is a kind of novel dissipative cell of many Tall Frameworks or other form of structure, there is initial stiffness large, small vibration distortion power consumption obviously, plastic deformation ability is large, hysteresis loop is full, energy dissipation capacity waits well various advantages energy, is a kind of outstanding dissipative cell.
Accompanying drawing explanation
Fig. 1 is main-vision surface structural representation of the present invention;
Fig. 2 is side structure schematic diagram of the present invention;
Fig. 3 is decomposing schematic representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated:
Embodiment 1
A kind of apleuria Low Yield Point Steel shear plate damper, comprise core steel plate 5, left side flap listrium 3, right side flap listrium 4, top flange plate 1 and bottom wing listrium 2, core steel plate 5 is connected by melt-through weld with left and right side frange plate 3,4, core steel plate is connected by melt-through weld with upper and lower frange plate 1,2, and left and right side frange plate 3,4 is connected by melt-through weld with upper and lower frange plate 1,2; Described core steel plate adopts the high ductility steel of low-yield, and strength classes of structural steel is selected Q100, Q160 or Q225; Described left and right side frange plate adopts common iron, the similar dumb-bell shape of shape; Described upper and lower frange plate adopts common iron, opens some bolts hole, does the use connecting.
In above-mentioned apleuria Low Yield Point Steel shear plate damper, between core steel plate and left and right listrium, upper and lower frange plate, answer continuous sequence, reduce the impact of welding on low-yield core steel plate as far as possible; Because core steel plate Out-of Plane Stiffness is less, should be respectively damper four columns for supporting are installed between frange plate up and down, avoid in transportation, generating plane is installed is out of shape outward, keep the firm safety of steel plate, after installing, should excise this four root post.
Experimental results show that, the apleuria Low Yield Point Steel shear plate damper that the present invention proposes, traditional hysteresis type damper is improved appropriately, by common core board steel plate is replaced by low yield point steel plate, can well improve the performance of traditional hysteresis type damper, have small vibration distortion power consumption obviously, hysteresis loop is full, the advantage that energy-dissipating property is good.Can believe, once Low Yield Point Steel starts large-scale production application in China, will promote effectively the marketization application of the superior shear plate damper of this energy-dissipating property.
