Description
Technical field
The utility model relates to a kind of energy-dissipating and shock-absorbing building, relates in particular to a kind of pitch-sand cushion and rubber bar energy-dissipating and shock-absorbing building.
Background technology
China is the country of earthquake more than, and the violent earthquakes such as the Xingtai in the 60 to 70's, Haicheng City, Tangshan have brought huge disaster to the people's lives and property.In the Wenchuan earthquakes in 2008, the broken ring of building is serious, and particularly in the building of villages and small towns, 80%～90% is masonry structure, and because it is not provided fortification against earthquakes or inferior seismic countermeasure, a large amount of houses destroy and collapse, and the earthquake especially severe is the antidetonation weak link.7.1 grades of earthquakes occured again in China Yushu district, Qinghai area in 2010, and the masonry structure earthquake is serious, the thousands injures and deaths, and another leaves our most bitter lesson for.The technical measures of thrifty practicality are the most effective antidetonation approach.Earthquake and the analysis showed that has together elongated horizontal fracture at wall base place, superstructure can be slided at this horizontal fracture, has effectively realized energy-dissipating and shock-absorbing, and the top earthquake is different from or is lighter than seamless building, a kind of successful energy-dissipating and shock-absorbing measure that Here it is.At present pre-earthquake-proof, antidetonation mitigation become the severe problem that the antidetonation scientific research personnel faces already.
Traditional Seismic Design Method is to guarantee structural seismic resistance safety by intensity and the deformability that improves structural element, and namely by strengthening sectional dimension of members and arrangement of reinforcement, the methods such as the raising rigidity of structure are strengthened the shock resistance of structure.But the materials of structure are many, the rigidity of structure and quality also increase thereupon, geological process is also larger, the energy that causes fabric structure to absorb increases, these dissipation of energies are again to produce inelastic deformation by member, the crack occurs or destroy realizing, structure failure or collapse consequently, can not really play the effect of energy-dissipating and shock-absorbing, repeatedly seismic demage analysis shows, the method is both uneconomical also not necessarily a good anti seismic efficiency.
In the prior art, the sliding and shock isolation technology has become a kind of novel architectural vibration-insulation technology.But traditional shock insulation adopts take rubber earthquake isolation support as main base isolation, and this vibration-isolating system technology maturation is also used in Practical Project, but because its cost is high, therefore multiplex in important building structure.In addition, other has small part is pure frictional slip vibration-isolating system, and that used sliding and shock isolation device is difficult to realize is spacing, reset.For example existing " sliding isolated bearing ", though have simplely, the advantage such as cost is low, isolating affection is remarkable can not self-resetting, need add in addition complicated spacing, resetting means, the infinite place earthquake isolating equipment can be excessive because of slippage, causes the slippage unstable phenomenon.
Along with the deep development of scientific research and scientific experimentation, imagination and the way of various control shakes, energy-dissipating and shock-absorbing are arisen at the historic moment.The metal damper of current architecture configuration energy-dissipating and shock-absorbing technology, such as U-shaped, X-shaped, triangle, that plastic strain by metal material comes earthquake energy, in building structure, generally being installed in herringbone supports, by shear strain, force metal damper to produce flexural deformation, thus earthquake energy.Its structure is complicated, and cost is higher, and power transmission is not direct, and material use efficient is not high.
Along with the fast development of Domestic Automotive Industry, China's junked tire amount surge, the junked tire amount is only second to the U.S. at present, occupies the second place of the world.Tire is rubber, belongs to heat cured polymeric material, is difficult under field conditions (factors) degrade, if abandon it in the earth's surface or be embedded in the soil, the more than ten years all undergo no deterioration or rot, and land occupation is gone back in the accumulation of scrap rubber, contaminated environment affects residents ' health and fire hazardous.But rubber has higher elastic performance and good anti-fatigue performance simultaneously, and good damping characteristic is arranged.Compare with other constructional materials, its characteristics are as follows: 1. the modulus of elasticity of rubber bar is less; 2. stress-strain diagram does not have obvious yield point; 3. larger elastic deformability; Can from moderate finite deformation, recover when 4. external force removes.
