摘要： PURPOSE:To let vibration of a bridge be damped quickly by letting a highly viscous material and a thin sheathing material be laminated monolithically with at least one of an upper and a lower chord member of the bridge. CONSTITUTION:A highly viscous material 11 and a thin sheathing material 12 are laminated monolithically with the lower surface of the lower chord member 7 of a truss bridge 5 in such a way that the highly viscous material 11 comes inside so that a vibration restraining device 10 is formed. In this case, rubber asphalt is preferably used as the highly viscous material 11 in such a state as being monolithically bonded roughly all over the lower surface of the lower chord 7 with adhesives 7 and the like. A steel plate is used as the sheathing material 12 which is made thin in thickness to the extent that the stiffness of the truss bridge 5 is not affected.

摘要： PURPOSE:To effect vibration damping action irrespective of natural frequency by projecting out relatively movably superposed operating pieces from the side face of each of a wall member and a framework and integrally providing a viscous body between respective operating pieces. CONSTITUTION:A plurality of operating pieces 10 are alternately provided on, e.g., the mutually opposite side faces of wall members 3, 3 being superposed relatively movably along the face direction, and a sheet type viscous body 6 is integrally provided between respective pieces 10. A mixture of asphalt and rubber, etc., is used for the viscous body 6. When the shape of a building caused by earthquake, etc. occurred, the body 6 is deformed because of the relative movement between structure bodies or the pieces 10 which is generated accompanying the shake of the building to absorb vibration energy, generating a vibration damping action. Hence, the vibration damping action can be effected irrespective of natural frequency, and the device can be miniaturized while facilitating an executing property.

摘要： PURPOSE: To damp building vibration effectively while maintaining a high degree of freedom in building planning by assembling earthquake resisting walls from a wall body, and connector plates and brace plates both incorporated in it, and interposing a viscous or viscoelastic material between the wall body and the connector plates. CONSTITUTION: An earthquake resisting wall 3 comprises a wall body 4, connector plates 5 of steel incorporated in both ends of the wall body 4 so as to be connected at both ends to beams 1 and 2, and brace plates 6 of steel embedded in the wall body 4 so as to be connected at one end to the connector plate 5 and at the other to the beam 1 or 2. The space left in rectangle-sectioned through holes 4a cut in the wall body 4 to accept the connector plates 5 loosely is filled with a viscous or viscoelastic material 7. The earthquake resisting wall 3 thus has a seismic control function of damping and absorbing by itself vibrational energy by external force, to thereby ensure earthquake resistance and seismic control of buildings and, when used typically as a partition wall, elevate the degree of freedom in the planning and structural design of buildings.

摘要： PURPOSE:To control easily the vibration of a tower, etc., by rotating a plurality of rotating bodies separately at the periphery of the upper part of a tower-like construction, and controlling the composition of forces of rotation so as to make the same period and the reverse direction with the motion of the tower-like construction caused by wind. CONSTITUTION:Hollow ring shaped housing bodies 3 and 3 are supported to the periphery of the upper part of a tower-like construction 1 by supporting members 2. After that, traveling trucks 5 and 6 as rotating bodies are interlocked with a rail 4 constructed inside the housing body 3 so that they are capable of making periodic rotation more than two. Then, a sensor 7 measuring the motion which occurs in the construction 1 by external force and a controller controlling the running of the trucks 5 and 6 based on the result of measuring are provided. The rotational period of the trucks 5 and 6 is controlled as same as the vibration period of the construction 1 and, at the same time, the direction of rotation and the phase are controlled to influence the composition of forces of rotation to the reverse direction to the moving direction of the construction 1. According to the constitution, even in a tower, etc., having no sufficient space, the vibration can be easily controlled.

CONSTITUTION:For example, a device 1 consists of a tank 2 mounted to the rooftop B1 of a building and liquid W kept in the tank. The tank 2 is constituted of the bottom side horizontal section 3, vertical sections 4 and 4 and the upper side horizontal section 5, the inside of the tank is divided into a plurality of tubes 7 by partitions, and an orifice 8a is respectively formed on about central part of the horizontal section 3. A stored amount of the liquid W in the tank 2 is set so that a lengthwise vibration period is equal to a natural vibration period of the building and the damping of vibration of the liquid W is controlled by the orifice 8a. Accordingly, the vibration of the building can be damped effectively.
