摘要： PURPOSE:To keep excellent vibration control effect even when the function of active type control is damaged on account of a rare accident by applying a high damping device to the frame of a structure together with a variable damping device or a variable rigid device. CONSTITUTION:A reverse V-shaped brace 33 functioning as a vibration control element is provided in the frame of a column and a beam, and a variable damping device 1 being an active type vibration control device and a high damping device being a passive type vibration control device are arranged in parallel between a beam 32 and the brace 33. Only the variable damping device 1 is controlled according to external force such as an earthquake and wind or the like and the response of a structure. In a state where the variable damping device 1 is locked, only the high damping device 21 functions.

CONSTITUTION:A pendulum system dynamic vibration reducer is constituted of a wire 12 whose suspending length is adjusted so as to synchronize with a natural period of a structure by suspending a weight 11 having prescribed mass. The weight 11 of the dynamic vibration reducer is pulled further in the horizontal direction by a wire 13, and the wire 13 is fixed by a wire fixing device 14. A variable stroke type fixing device 41 having a wire winding - rewinding mechanism such as a motor and a pulley 43 is used as the wire fixing device 14, and prescribed initial displacement is given by the winding - rewinding mechanism, and fixation is released when it is controlled, and the wire 13 is loosened, and the weight 11 is vibrated in large amplitude, and rising characteristics of the dynamic vibration reducer are improved.

摘要： PURPOSE:To decrease the response of a building effectively in accordance with characteristics of external disturbance caused by wind, earthquakes, etc.. CONSTITUTION:An upper vibration control system A forming an active type vibration absorber is provided to the top of a building, and active type or passive type lower vibration control systems B are provided to floors from the first to the third of the lower part of the building. The upper vibration control system A regards the weight of the uppermost layer of the building as a weight, and the movement thereof is controlled with a variable damping device 1a to deal with wind vibration. Vibration control devices of a variable damping device 1b, etc., are incorporated into the lower vibration control systems B between an inverted V-shape brace 35 and a beam 34 in a column and beam framing 31, and the vibration control device is functioned to deal with an earthquake.

摘要： PURPOSE:To prevent surely the generation of large deformation in a fame, and to display the deformability of a damper section by bridging a spacing material in length equal to a distance between overhanging members between the front ends of the parallel overhanging members. CONSTITUTION:A plasto-elastic damper 2 composed of damper sections 21, 21 on both sides formed in the shape of a body of revolution and a connecting section 22 between the dampers is spanned between overhanging members 1, 1 overhung in parallel from one S of structural materials S, S' detached at a distance. Both ends of the plasto-elastic damper 2 are joined with the overhanging members 1, 1, and the connecting section 22 is coupled with a coupling member 4 connected to the other structural member S'. In the structure, a spacing material 6 in length equal to a distance between the overhanging members 1, 1 is bridged between the front ends of the parallel overhanging members 1, 1. The rigidity of a frame F consisting of the overhanging members 1, 1 and the plasto-elastic damper 2 is increased, thus positively displaying the deformability of the samper sections 21, 21, then effectively absorbing energy.

摘要： PURPOSE:To secure safeness of a variable damper device as well as reduce the amount of response of structure by permitting the combined evaluation of the resonance and damping property of the structure by a method in which damping coefficients are made variable for the closing and opening cases of a great flow-switching valve. CONSTITUTION:Oil-pressure chambers 5 are provided on the left and right sides of a piston 3 reciprocally moving in a cylinder 2. The piston 3 is fixed or made movable by closing or opening a great capacity switching valve 10. A shut-off valve 11 is also provided on the back pressure port 14 side of the valve 10 to allow a great volume of pressure oil to flow to the valve 10 at high speeds or to interrupt in instantly. When the valve 10 is closed, a bypass thought which pressure oil is allowed to flow under a throttled condition is provided. Orifices 15 and 16 are adjusted to set up the damping coefficient to a variable or optional value when closing or opening the valve 10.

摘要： PURPOSE:To obtain a vibration absorber excellent in quake damping and pressure regulating effects by providing the first vibration system of pendulum type made possible to vibrate in two directions X, Y and vibrating in a different period for the respective directions in accordance with the primary natural period in the two directions X, Y of a structure. CONSTITUTION:A pendulum 10, constituting the first vibration system for a structure 30 of main vibration system, forms a weight 11, concurrently serving as a supporting bed using a steel material, hung down by wire ropes 12 in four points for a peripheral frame 2 of a device. Next the weight 11 mounts on its upper a water tank 20, filled with water constituting the second vibration system, and the wire rope 12 mounts to its both sides a guide member 3 extending in a direction X in a bottom side of a beam part of the peripheral frame 2. The first vibration system is constituted of the pendulum made different in its vibration period between two orthogonal directions X, Y, and their vibration period is simultaneously controlled. In this way, a single device can cope with vibration, and the device is compact possible to sensitively react even for small vibration.
