Technical field

The present invention relates to technical field of structural engineering, be specifically related to the anti-buckling shear plate damper of a kind of Low Yield Point Steel.

Background technology

As the dissipative cell of many Tall Frameworks, traditional Low Yield Point Steel shear plate damper has had good energy-dissipating property, but it can produce flexing outside excessive face when larger ratio of height to thickness, has affected significantly the energy-dissipating property of damper.

In order to solve this shortcoming of traditional Low Yield Point Steel shear plate damper, present patent application has proposed a kind of novel shear plate damper, i.e. the anti-buckling shear plate damper of Low Yield Point Steel.By arranging in core board both sides laterally and vertical anti-buckling stiffening rib, the face that has well retrained damper is out of shape outward, and between stiffening rib long side direction and core board, stay and establish certain gap, can give full play to the strengthening ability of core board steel plate under repeated deformation effect.In addition core steel plate adopts low yield point steel plate, its major advantage shows: (1) is because Low Yield Point Steel is compared with common iron and had identical modulus of elasticity, poisson's ratio, therefore the dissipative cell of 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, there is plastic strain, dissipation effect energy structurally, (3) duty of shear plate damper in pure shear, stressed even, can bring into play fully to greatest extent its energy-dissipating property.Comprehensive above-mentioned advantage, the anti-buckling shear plate damper of Low Yield Point Steel 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, provide a kind of Low Yield Point Steel anti-buckling shear plate damper.

The object of the invention is to be achieved through the following technical solutions:

The anti-buckling shear plate damper of a kind of Low Yield Point Steel, comprise core steel plate, horizontal anti-buckling stiffening rib, perpendicular anti-buckling stiffening rib, left side flap listrium, right side flap listrium, top flange plate and bottom wing listrium, core steel plate respectively with a left side, right side flap listrium and upper, bottom wing listrium connects by melt-through weld, the minor face two ends of horizontal anti-buckling stiffening rib respectively with a left side, right side flap listrium is welded to connect, the minor face two ends of perpendicular anti-buckling stiffening rib are respectively with upper, bottom wing listrium is welded to connect, between the long limit of horizontal anti-buckling stiffening rib and perpendicular anti-buckling stiffening rib and core steel plate, all stay and establish certain gap, left, right side flap listrium and upper, bottom wing listrium connects by melt-through weld.

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 grade is selected Q100, Q160 or Q225.

2. the anti-buckling stiffening rib described in adopts common iron.

3. the left and right side frange plate described in adopts common iron, the similar dumb-bell shape of shape.

4. the upper and lower frange plate described in adopts common iron, has some bolts hole, does the use connecting.

The present invention has following useful effect:

The anti-buckling shear plate damper of low surrender steel 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, the outer flexing of face is little, plastic deformation ability is large, hysteresis loop is full, and energy dissipation capacity waits well various advantages energy, is a kind of outstanding dissipative cell.
