摘要： PURPOSE:To cope with earthquake as well as environmental vibration by providing a first resisting member for eliminating micro displacement vibration having amplitude lower than a predetermined level and a second resisting member for eliminating large displacement vibration having amplitude higher than the predetermined level. CONSTITUTION:When a resisting member 18 in a vibration eliminating damper 10 is subjected to micro displacement vibration having amplitude smaller than a predetermined level, resisting portion 18A being lowered by a load while resisting against a spring 16 vibrates while being subjected to resistance is viscous liquid 14 so as to damp vibration. Since a wire 20 is loosened, vibration is not transmitted to a resisting member 22 for large displacement vibration. Upon application of large displacement vibration having amplitude higher than the predetermined level due to earthquake, the resisting section 18A vibrates considerably and the vibration is transmitted through the wire 20 to the large displacement resisting member 22. The resisting section 18A is subjected to resistance when it moves upward and lowers, and such motion is repeated to damp vibration. Consequently, the damper can cope with large displacement vibration as well as environmental vibration of micron order.

摘要： PROBLEM TO BE SOLVED: To simply install in a simple structure by a method wherein a vertical support function is provided between the upper and the lower structures and horizontal vibration transmitted from the lower structure is dampened and kinetic energy at the upper structure arising from horizontal displacement is absorbed. SOLUTION: Load of an upper structure G is transmitted to a lower structure B through a base isolation support device, and horizontal vibration of the upper structure G is prevented. For a strong wind working at the time of typhoon or the like as a side wind on the upper structure G whereon an uplift preventing device S is installed, the upper structure G is built in lightweight while lateral rigidity is made small for the base isolation support device. For uplift arising from horizontal vibration, resistance is made by vertical rigidity of the uplift preventing device S, and the horizontal vibration is absorbed by energy absorption of the base isolation support device. When a seismic motion occurs, shaking of the upper structure G caused by vibration at a foundation B is changed into vibration of long cycle by the base isolation support device. Then vibration can be dampened by absorption of energy caused by plastic deformation of lead plugs of the base isolation support device.

摘要： PROBLEM TO BE SOLVED: To provide superior damping effect from slight vibration such as traffic vibration to an earthquake by providing a load support part comprising alternately laminating a viscoelastic body and a reinforcing plate and an energy absorption part arranged in the hollow part of this load support part and constituting the energy absorption part from a column-shaped lead body and a viscoelastic layer. SOLUTION: A base isolation support device 1 comprises alternately laminating a viscoelastic body 5 and a reinforcing plate 6, a reinforcement mounting plate 7 having its hole for fitting dowel pin 4 is provided at both end parts of that laminating direction, and each of component members 5 to 7 is laminated and integrated by curing and adhering them. A hollow part 8 piercing through in the laminating direction is formed at the center part of the device 1, and a lead body 10 having a viscoelastic layer 9 around its body is densely sealed in this hollow part 8. Thereby, when great horizontal displacement acts on the base isolation support device 1, for example, by a large-scale earthquake, shear deformation is generated in the reinforcing plate 6 and the viscoelastic body 5, and earthquake energy is speedily absorbed by subsequent plastic deformation of the lead body 10.
