Abstract
The present invention relates to a frictional energy consumption type anti-seismic structure which has the technical scheme that the integral structure of a building is divided into more than two parts along a vertical direction or a horizontal direction, or a local structure is separated from the integral structure, and an anti-seismic seam is arranged between the local structure and the integral structure; sliding nodes are arranged in the seam and are connected with each other in a sliding manner dampers which are fixed to building elements on both sides, and at least one pair of friction plates are connected with each other by a high-strength bolt and can slide correspondingly along a single horizontal direction, two horizontal directions or three space directions. The present invention is suitable for frame shearing structures, shear wall structures and barrel body structures.
Description
The present invention relates to a kind of earthquake-resistant building structure.
The antidetonation of building structure normally strengthens the globality of building, relies on the interior friction of structural meterials, mainly is that plastic strain generation damping consumes seismic energy, that is to say the permanent damage that relies on agent structure even destroys the seismic energy that dissipates.The problem that this method exists is:
1. agent structure had both been born vertical load, bore the function that consumes seismic energy again, and especially vertical bearing carrier is because of plastic strain makes horizontal displacement excessive, easy when shaking greatly
Play building collapsing.
2. during earthquake, structure enters the plasticity duty and starts late, and promptly main energy consume mechanism works later, the intrinsic frequency of building is difficult to avoid seismic frequency again, the opposing seismic forces often produces resonance, causes structure to bear huge seismic forces, for need consume a large amount of structural meterialss.
3. be in the plasticity duty when structure consumes energy in a large number, therefore distortion is very big, and then the non-structural failure of building is serious, and after the earthquake, the permanent set of structure is bigger.
4. after the big shake, though structure can be avoided collapsing, damage is serious, is difficult to repair.
At present, the antidetonation of building structure also has the method for taking freely movable bearing in building main body and basic junction, cutting down the shearing force that earthquake produces, but also has some problems, and for example, freely movable bearing employing rubber pad can not be applicable to highrise building; Also have the method that adds mass on the roof, but need computer control, often maintenance, and also reliability is relatively poor, and cost is higher; On the basis, add shock insulation damping device, mostly be than complicated facility and spring etc.
The objective of the invention is overall structure or certain local building unit are separated, rely on it
Produce friction energy-dissipating and reach damping.
Frictional energy consumption type antiseismic structure of the present invention be with the overall structure of building vertically or horizontal direction be divided into two with top, perhaps partial structurtes are separated with overall structure, establish absorbing joint therebetween, establish sliding node in the seam, connect by the slip damper.
The slip damper is fixed on the side pieces, is made up of at least one pair of friction plate and high-strength bolt, and one of them friction plate is provided with slotted hole, and another friction plate is provided with circular hole, two frictions
Bolt connects, and can slide relatively along slotted hole, and two pairs can be connected with upper friction plate,
But hole horizontal single-headed, horizontal bidirectional or space three-dimensional are provided with.
Above-mentioned overall structure can be a frame structure, and absorbing joint is vertical with it
Between shear wall and frame column, the beam.
Above-mentioned overall structure can be a shear wall structure also, and absorbing joint is vertically cut apart it, sliding node
Between wall and wall.
Overall structure can be the outter frame inner cylinder structure, and absorbing joint is vertically cut apart it, and sliding node is located at
Tube and framework intersection.
Overall structure can also be the bundled tube structure, and absorbing joint is vertically cut apart it, and sliding node is located at tube
The tube intersection.
Absorbing joint can be with the overall structure divided in horizontal direction, and sliding node can be located between building top layer and the lower floor.
When earthquake took place, each separating part of building produced limited slip and friction along the slotted hole direction of slip damper, thereby has consumed seismic energy, has reduced seismic amplitude, makes structure be in elastic state substantially, and shock resistance improves greatly.
After the earthquake, structure resistance becomes elastic restoring force, as long as kinetic force of friction recovers less than elasticity
Structure position changing can most ofly recover, and its permanent set is big or small relevant with the force of sliding friction size, is to eliminate permanent set, only needs to unclamp high-strength bolt at the sliding node place, and after recovering fully to be out of shape, row is tightened again
State before structure and the earthquake is as good as.
Advantage of the present invention is:
1. frictional energy consumption type antiseismic structure consumes energy traditional structure everywhere and becomes the concentrated power consumption of slip damper, ensures that agent structure is not subjected to or few damaged.Slip joint is lighted on-off action, when structure is carried at general wind
Under the less geological process, node does not slide, and structural entity work is the same with ordinary construction; Work as earthquake
After being increased to a certain degree, sliding node starts voluntarily, beginning slippage, friction member power consumption.By
The size of reason design frictional force can make structure at elastic state fully, just is subjected to very big damping
With, reduce earthquake response.
2. after sliding node starts, frequency conversion taking place, make structure forfeiture intrinsic frequency, avoids resonance automatically.
3. for the structure of vertically cutting apart, because friction energy-dissipating member and vertical load transfer route are irrelevant, therefore vertical bearing carrier is not subjected to plastic deformation energy dissipation's influence, has strengthened stability
The slip damper is manually designed, to resist brisance greatly.
4. when shaking greatly, structure is in elastic state, or enters plasticity
Agent structure is avoided damage, can recover most of distortion again after earthquake, and permanent set
The structure of vertically cutting apart, as want to eliminate permanent set, measure also is simple and easy to
Earthquake goes out
Structure still is in original duty.
5. structure is separated during owing to big shake, and rigidity die-offs, and it is less to bear seismic forces, can save a large amount of structural meterialss.
6. because malformation is less, can alleviate the unstructuredness damage.
7. the slip damper structure is simple, practical and reliable, timeliness is very little, and low cost is convenient to promote.
Below in conjunction with accompanying drawing, embodiment the present invention is elaborated:
