摘要： PURPOSE:To make effective base isolation and vibratory suppression of horizontal and vertical vibrations by installing consolidatedly a horizontal tremor absorbing part to absorb horizontal tremors, a vertical vibration absorbing part to absorb vertical tremors, a restraining member for deformation in the vertical and horizontal directions, and a vertical vibration damping member. CONSTITUTION:A tapered portion 12a of a steel rod is formed from a restraining member 12 for deformation in the vertical and horizontal directions. A clearance 14 is provided between an upper flange 8 of a horizontal vibration absorbing part 5 situated under and a taper hole 13 penetrating a lower flange 10 of a vertical vibration absorbing part 6. Horizontal deformations exceeding this size are restrained by the clearance 14. Horizontal vibrations are mostly absorbed by the absorbing part 5 situated under. The vertical vibration of the ground is absorbed by the absorbing part 6 to the extent of the clearance 14. The resonance of the absorbing part 6 for the vertical vibration is damped by a damping member 15. Thereby base isolation and vibratory suppression of the structure can be made effectively using a device in which the prevention of seismic tremors and environment vibrations is incorporated consolidatedly.

摘要： PURPOSE:To obtain vibration resistant rubber capable of coping with share deformations in the diagonal direction to a satisfactory extent by alternately laminating radially bored metal plates with rubber, changing the distance from the center for every plate and integrally molding them in such a way that rubber holes are continuously formed. CONSTITUTION:Vibration resistant rubber 1, which are interposed between a foundation and a building, are alternately laminated with metal plates 2 which vary with a distance from the center for every plate and have radially bored holes 2a and rubber 3 in such a way that the rubber 3 is formed continuously and integrally through the holes 2a. In addition, the holes 2a at the corners formed in the shape of smoothly curved surface, thereby preventing the concentration of stress in the corners and protecting the rubber from rapture. This compensates the bonding between the metal plates 2 and the rubber 3 at their interface. This construction makes it possible to obtain vibration resistant rubber capable of coping with rolling during earthquake to a satisfactory extent.

摘要： PURPOSE:To facilitate any adjustment of natural frequency by screwing a damping device made up of attaching a weight tight to both ends of a plate spring in a column via a shiftable spring washer, and simultaneously attaching weight tight to a fixed plate via a damper. CONSTITUTION:A damping device U made of attaching a weight 11 tight to a column 4 erected on a fixed plate 2 via a plate spring 6 is attached to a frame 1 by a bolt 3 in altering its arrangement in space between two underfloor beams 16 and 16. In addition, this plate spring 6 is attached to the column 4 through a clamped upper plate 5 and a freely fitted lower plate 7 via a shiftable spring washer 8, while the weight 11 and the fixed plate 2 both are attached via a damper 13 consisting of a viscoelastic body. Then the weight 11 is rocked as centering on a support point by means of the spring washer 8 and absorbs the vibration, while the support point of the weight 11 is separately shifted to some extent, thereby performing the adjustment of natural frequency. With this constitution, an optimum vibro-damping characteristic is 70 by simple structure.

摘要： PURPOSE:To cope with from a small earthquake to a large earthquake when a multi-bypass cylinder is used for a damper used in a floor isolation method of a building. CONSTITUTION:A multi-bypass cylinder is constituted of a cylinder 10, a piston 11 fitted in the cylinder 10, a plurality of flanks 12 and electrodes 13 and 14 provided to the flanks 12. The cylinder 10 and flanks 12 are filled with electric viscous fluid. The flanks 12 are connected to first and second spaces 15 and 16 partitioned by the piston 11 in the cylinder 10. Voltage is applied to electric viscous fluid flowing in the flanks 12 by the movement of the piston 11 every flanks 12 from the electrodes 13 and 14, so that viscosity of the electric viscous fluid can be increased to change damping force of the multi-bypass cylinder. Value of damping force can be greatly changed because there is a plurality of flanks 12 in the multi-bypass cylinder.

摘要： PURPOSE:To obtain the excellent braking damping effect between two members by obtaining the plasticity with the twist deformation of a steel pipe having the high shearing yield to absorb the deformation energy, and positively evaluating the hysteresis absorbed energy to absorb the deformation energy efficiently. CONSTITUTION:A top plate 2 and a base plate 3 are arranged in parallel with each other with a space, and a steel pipe 5 is arranged between these plates, and while the steel pipe 5 is bonded to the top plate 2 strongly. A displacement transmitting part 7 provided in the base plate 3 is engaged with a twist plate 6 fixed to the steel pipe 5. At the time of earthquake, the top plate 2 and the base plate 3 are displaced relatively to transmit the rotation as the displacement quantity thereof to the twist plate 6 through the displacement transmitting part 7. The twist moment is thereby applied to the steel pipe 5.
