Description

The multidirectional shock insulation of level, vertically pulling-resistant marmem-rubber combined bearing
1. technical field
The utility model relates to a kind of marmem-rubber combined bearing with the multidirectional shock insulation of level, vertically pulling-resistant ability, belongs to building structure damping control field.
2. background technology
In the damping control field of building structure, be a kind of comparatively ripe Passive Control technology by using rubber earthquake isolation support relief features seismic response.The isolator that is most widely used in engineering shock insulation field at present is General Purpose Rubber bearing and lead core rubber support.The block rubber vertical rigidity is little though the General Purpose Rubber bearing has overcome, shortcoming such as poor stability under the horizontal loads, but because the little power consumption of the damping of rubber own is not enough, the bigger bearing unstability that causes of shock insulation layer distortion can cause owing to can obtain damping effect preferably so it must be used just with other damper.This support style of lead core rubber support mainly utilizes the power consumption of plumbous shear extrusion flow mechanism, and energy dissipation capacity is stronger, and bigger damping force can be provided, and has damping effect preferably.But can't recover self original shape after the lead for retractable pencil plastic strain, thereby greatly reduce the automatic recovery ability of this type neoprene bearing.Above-mentioned deficiency has become the principal contradiction that hinders architectural vibration-insulation further to promote.Therefore, the more superior novel bearing of development performance becomes the development priority of present stage various countries' seismic isolation technology.
Marmem (Shape Memory Alloy is abbreviated as SMA) is a kind of new function material and intellectual material.Compare with common material, it has characteristics such as unique shape memory effect, superelastic effect.Utilize the energy-dissipating device of super elastic shape memory alloy effect design to have durability and corrosion resistance and good, the operating period limit for length allows advantages such as large deformation and distortion can recover.Based on the performance of above-mentioned excellence, experts and scholars begun with marmem be used to build, the development of the novel shock isolating pedestal of bridge.
" University Of Tianjin's journal ", in November, 2002, the 35th volume " the high building structure intelligent shock-isolation of applying shape memory alloy " (document 1 is called in letter in this paper summary of the invention and the description of drawings) proposed the compound normal stack rubber vibration isolation cushion of a kind of shape-memory alloy wire mixing earthquake isolating equipment.This device adopts the marmem drag-line of ordinary rectangular neoprene bearing in two pairs of intersections of four sides difference symmetric arrangement, and they are in normal temperature martensitic state and normal temperature austenitic state respectively.Marmem drag-line two ends are individually fixed on the outer connection steel plate of neoprene bearing, in addition, attemperating unit are housed also on the drag-line.The compound normal stack neoprene bearing of this kind marmem is installed on the substrate of building structure, if meet with strong geological process, utilize the hyperelastic deformation of austenitic state marmem drag-line, the elastic-plastic deformation of martensitic state marmem drag-line and the shearing lag return distortion dissipation earthquake motion energy of rubber, reduce the distortion of shock insulation layer.After vibration finished, if there is permanent set in bearing, the temperature of the martensitic state marmem drag-line that can raise utilized its shape memory effect that structure is resetted.The temperature of attempting to change martensitic state marmem drag-line in the vibration processes is adjusted the horizontal rigidity and the damping of bearing, to adapt to the stochastic behaviour of geological process.This mixing earthquake isolating equipment weak point is: the marmem drag-line does not apply prestretched, and a pair of in the vibration processes in two of the bearing side arrangement pairs of drag-lines will be lost the power consumption effect because of the pressurized flexing, can not improve the vertically pulling-resistant performance of bearing simultaneously; Because the two ends of drag-line are fixed on four sides of neoprene bearing, little thereby the less energy intensive of the hyperelastic deformation of marmem and can only play certain power consumption effect to the earthquake motion of two orthogonal directions of horizontal plane, but, be not enough to guarantee that any horizontal direction geological process undersetting all can produce isolating affection preferably to top-out to the earthquake motion energy dissipation capacity deficiency of other horizontal direction; The reaction speed of marmem is slower during heating and cooling, takes longlyer, and hysteresis effect is obvious, therefore above-mentioned utilize shape memory effect carry out building structure in real time half active control strategies of control be difficult in engineering, implement.
" world's earthquake engineering " in December, 2003, the 19th volume the 4th phase " design of the rubber combined bearing of SMA-and isolation property " (document 2 is called in letter in this paper summary of the invention and the description of drawings) has proposed a kind of marmem-rubber combined bearing from the angle of passive shock insulation.It is by two blocks of connection steel plates, two groups of shape-memory alloy wire and laminated rubber bearings that intersect are formed up and down.Two groups of shape-memory alloy wires all are in the normal temperature austenitic state.Shape-memory alloy wire is connected with the steel plate that is bonded in the rubber pad two ends after prestretched.Under geological process, laminated rubber bearing is brought into play its shock insulation function, and when two-layered steel plates produced relative horizontal movement up and down, two groups of shape-memory alloy wire co-operation of intersecting were by they hysteretic energy ability earthquake energy under hyperelastic deformation.Because the effect of shape-memory alloy wire, can overcome that the displacement of General Purpose Rubber bearing shock insulation layer is excessive, occur deficiency such as permanent set after the shake of lead core rubber support lead for retractable pencil.Yet shape-memory alloy wire is symmetrically fixed on the both sides of rubber pad in the above-mentioned bearing, and the super-elasticity dilatation of shape-memory alloy wire is very little under the geological process, causes super-elasticity damping hysteretic energy scarce capacity; This bearing can only be given full play to the super-elasticity damping energy dissipation at the horizontal earthquake excitation that is parallel to plane, shape-memory alloy wire place and do in order to reach comparatively ideal isolating affection, power consumption effect to the seismic stimulation of other horizontal direction is very weak, and is therefore relatively poor to the compliance of horizontal earthquake action input direction.
