Description
Technical field
The utility model is a kind of lead-buckling-restrained supporting composite energy dissipation device, belongs to the energy consumer field of building structure.
Background technology
Tradition supports has the history in more than 30 year nearly as energy-consumption shock-absorption device, because its easy construction, cost economy is calculated simply, is extensively adopted by engineering circle.But tradition is supported on distinct issues are arranged in the antidetonation, be exactly it when big shake pressurized flexing unstability very easily, the inefficacy and the destruction of causing support itself and connected mode.In addition, the tension and compression hysteresis loop that tradition supports is asymmetric, and energy dissipation capacity is poor in big earthquake centre.The problem that how to strengthen tradition support anti-seismic performance has become Chinese scholars and engineering circle problem demanding prompt solution.
The Japan scholar has proposed not have the buckling-restrained support of bonding on the basis that tradition supports, this supports by mild steel steel plate 1, hard diaphragm material, outsourcing side's (circle) steel sleeve 2 and fill concrete 7 forms its organigram such as Fig. 1.Mild steel steel plate 1 is born axial load as the mild steel steel core, and outer tube provides cross binding by fill concrete 7, suppresses mild steel steel core pressurized flexing unstability.Contact surface along mild steel steel core and concrete seven scribbles the very thin hard diaphragm material of one deck, the shear strain that produces when being used for eliminating elongation of mild steel steel core and contraction, lateral expansion when regulating pressurized simultaneously, therefore the mild steel steel core can freely shorten in the aggregate of concrete seven and outer steel sleeve pipe 1 and extend, and surrenders power consumption repeatedly in big earthquake centre.
The anti seismic efficiency that does not have the buckling-restrained support of bonding is better than tradition to be supported, but its associated disadvantages is also arranged: this support is main to rely on the mild steel steel core in supporting to surrender the opposing geological process repeatedly, and the seismic energy of consumption is limited; The yield point of mild steel steel core is very low, and irrecoverable distortion takes place after surrender, easily causes the structure permanent deformation excessive in big earthquake centre; Simultaneously, this support is prone to deformity out of plane, and the lateral force that causes very easily makes the concrete slab edge damage under the early stage effect of earthquake.
Summary of the invention
Technical problem to be solved in the utility model is the shock resistance problem that significantly improves braced structures.For this purpose, the utility model proposes a kind of lead-buckling-restrained supporting composite energy dissipation device.
The technical scheme that lead of the present utility model-buckling-restrained supporting composite energy dissipation device adopts is: at lead-buckling-restrained supporting composite energy dissipation device mild steel steel plate 1 is set at the center, the mild steel steel plate 1 outer outer steel sleeve pipe 5 that is provided with, the two ends of mild steel steel plate 1 are connected with scab 3 by bolt 2, scab 3 is connected with junction plate 4 by bolt 2, internal layer band steel sleeve pipe 6 also is set between mild steel steel plate 1 and the outer steel sleeve pipe 5, perfusion lead layer 8, concrete perfusion 7 between steel sleeve 5 and the internal layer band steel sleeve pipe 6 outside in mild steel steel plate 1 and the flat sleeve pipe of internal layer 6 gaps.Because lead has low yield strength, high flexibility and high ductibility, can play the barrier film effect between mild steel steel plate 1 and the flat sleeve pipe 6 of internal layer, in deformation process, can absorb lot of energy simultaneously.
Described lead-buckling-restrained supporting composite energy dissipation device, at the peg 9 that is crisscross arranged on the mild steel steel plate 1 and on the inwall of internal layer band steel sleeve pipe 6, peg 9 height equate with mild steel steel plate 1 and flat sleeve pipe 6 gap sizes of internal layer, realizing operative constraint to mild steel steel plate 1, the power consumption effect of performance mild steel steel plate 1 constraint surrender and approach power consumption effect in the lead layer 8 extrusion shearing processes.
So this support has the characteristic of dual power consumption.This energy dissipating is supported in the structural dynamic reaction has stronger damping energy dissipation ability.
The utility model has utilized two kinds of energy consume mechanisms of plumbous shear extrusion hysteresis distortion and mild steel steel plate constraint surrender fully, and energy dissipation capacity is good.Damper belongs to bolt disassembly type damper, is convenient to change after destroying under the violent earthquake effect.
