摘要： PROBLEM TO BE SOLVED: To provide a vibration control device capable of reducing maintenance cost extremely. SOLUTION: In the device, which has a liquid storage space 2, in which a liquid having the same vibrational period as the vibrational period of a building is housed, and by which the vibrations of the building by wind load and the vibrational energy of an earthquake or the like are controlled, a nonvolatile liquid 4 as the uppermost layer of the liquid is mounted into the liquid storage space. According to the vibration control device 1, a contact between water and the outside air is interrupted and the evaporation of water can be prevented because the nonvolatile liquid constitutes the uppermost layer section and covers the upper section of water when the inside of the liquid storage space is filled with water, and the capacity of water in the liquid storage space can be kept constant at all times. Thus, maintenance such as the scheduled control of the quantity of water is made unnecessary.

摘要： PROBLEM TO BE SOLVED: To provide a seismic control damper capable of being simply applied to a wooden building at a low cost. SOLUTION: A pair of steel plates 1 and 2 respectively fixed to two members connected to each other in a joint section of a wooden framework are laminated in an in-plane relative rotatable manner by holding a viscoelastic material between both steel plates. The steel plates have body sections 1a and 2a for holding the viscoelastic material and mounting sections 1b and 2b fixed to two members. As a steel plate, plate-like steel plate, uneven-shape bent-up processed steel plate, L-shape bent steel plate, T-shape welded steel plate or the like can be adopted. The steel plates are mounted on two planes of structure on both sides of the joint section and are mounted on four planes of structure on the circumference of the joint section. A welded anchor hardware or a brace fixed harware can be set to the joint section between a column and a sill. Both steel plates are clamped with an expansion stop bolt 7. A projection cut into the member surface layer section is provided in the mounting section, and a burr or a cut-off is used for a projection when a hole is formed. Both wood screw and adhesive are properly used for fixing.

摘要： PROBLEM TO BE SOLVED: To provide a vibration control structure capable of greatly improving damping performance. SOLUTION: Vibration control devices such as visco-elastic walls 3 for absorbing and dispersing vibrating energy are provided at required positions in a two or more layered building and the main frames of the building are formed in a column precedingly yielding shape with the bending rigidity of columns 1 being smaller than the bending rigidity of beams 2. The bending rigidity of the columns is set to be 1/2 to 1/10 the bending rigidity of the beams. As the vibration control device, the visco-elastic wall 3 is suitably used which has a viscous body or a visco-elastic body is interposed in an adhered condition between at least a pair of steel plates laminated to be relatively displaceable at a space to cause small deformation with layer-to-layer displacement to show great damping force. Otherwise, a steel material based hysteresis damper can be used as the vibration control device with restoring property due to repeated load showing plastic hysteresis and thus hysteresis damping force is exhibited.

摘要： PROBLEM TO BE SOLVED: To reduce the vibration response at the time of earthquake, and to accurately understand the movement of a structure having a deep basement at the time of earthquake by filling a space between a side surface of a lower structure of a building structure and the ground with the viscous material. SOLUTION: A building structure 12 is formed of an upper structure 13 and a lower structure 14, and the lower structure 14 is formed of foundation piles 17 placed into the supporting ground 16 and a basement 19 positioned in the surface layer ground 18. A vibration control structure 11 is formed of the basement 19 and the viscous material 20, which is composed of asphalt and which is filled between side surfaces of the basement 19 and the surface layer ground 18, and the basement 19 is formed into the structure having a rigidity lower than that of the upper structure. With this structure, at the time of earthquake, the viscous material 20 functions as a damper so as to attenuate the vibration energy of the building structure 12. Furthermore, since the characteristic of the viscous material 20 is well known, influence of the mutual work of the side surfaces of the basement 19 and the surface layer ground 18 to the building structure 12 can be made clear, and an analysis model, which is obtained by integrally forming the upper structure 13 with the basement 19, can be formed for design.
