Description

Multidimensional subtracts the shock insulation lead core rubber support
Technical field
The utility model belongs to the damper technical field, is specifically related to a kind of shock insulation lead core rubber support that subtracts.
Background technology
Earthquake is the serious harm mankind's a natural calamity, has caused very heavy life and property loss to the mankind.Seimic engineering structures is destroyed, and causes painful casualties and serious economy loss, this with regard to an urgent demand engineers and technicians to the engineering structures effective seismic design that holds water.
Subtracting seismic isolation technology is easy, economic, advanced earthquake resistant engineering means, comprises two kinds of technology of shock insulation and damping.Wherein shock insulation is to utilize vibration-isolating system, the agent structure of managing to stop seismic energy to enter earthquake isolating equipment being installed, damping then is to utilize special cushioning members or device, makes it that rate is introduced into the plastic zone when macroseism, produce big damping, a large amount of consumption enters the energy of agent structure.By selecting suitable earthquake isolating equipment and the installation site of subtracting, size that can control structure internal force and distributing.Domestic and international project antidetonation personnel have researched and developed the earthquake isolating equipment that subtracts of many types, as neoprene bearing, lead core rubber support, sliding friction type vibration absorption and isolation support, elastoplasticity damping power consumption steel damper, MR damper, oil damper and the plumbous combination of steel energy-dissipating device etc.
By a large amount of seismographic record statisticses as can be seen, vertical earthquake peak accelerator and horizontal earthquake acceleration ratio are 1/2-2/3, and have obtained the seismographic record that vertical component of acceleration meets or exceeds the horizontal acceleration component.A large amount of earthquake disasters show that vertical earthquake can not be ignored the influence of works, and its effect surpasses horizontal earthquake sometimes, thereby also must give great concern to vertical seismic character.Yet the domestic and international at present research to seismic isolation technology mainly rests on the simple horizontal shock insulation, and is also rare to the research that realizes level and vertical earthquake isolating simultaneously.Above-mentioned these subtract earthquake isolating equipment also can only the solution level to the problem that subtracts shock insulation, do not reduce for vertical earthquake response.
1988, Japanese scholar rattan field acute hearing proposed to utilize the combining structure of traditional neoprene bearing and common spring, viscous damper carry out level to and vertical earthquake isolating, and carried out shaketalle test.But big with common spring and damper vertical rigidity, in limited range, can not provide and isolate the required damping of vertical earthquake, so its vertical energy dissipation capacity and isolating affection are very limited.Nineteen ninety-five, Chinese scholar professor Tang Jiaxiang takes the lead in proposing to adopt the approach that reduces the neoprene bearing vertical rigidity to study the vertical earthquake isolating problem, has started the precedent of China's research level and vertical earthquake isolating bearing.But because vertical support also is a said vertical support element simultaneously, need to keep enough rigidity and stability, in the scope that the neoprene bearing vertical rigidity can reduce, its vertical damping performance is also relatively poor, thereby its vertical earthquake isolating effect is not obvious equally.This shows that this engineering circle difficult problem of vertical earthquake isolating is not well solved.
