    摘要： A hydraulic cylinder type high damping device in which a cylinder member or a piston rod member is connected to the frame of a structure and the other member is connected to an earthquake-resisting element integrally secured to the frame. A plurality of passages through the piston connect hydraulic chambers on opposite sides of the piston. The passages are provided with pressure-governing valves which control the flow of oil between the hydraulic chambers. In addition, an accumulator system provides a bypass for oil to flow between the hydraulic cylinders in order to modulate the oil pressure in the damping device. Relief valves are provided in parallel with the pressure governing valves to provide a variable damping coefficient which protects the damping device from overloads caused by excessive seismic shock.

    摘要： A variable damping and stiffness structure is disclosed, which includes a variable damping device provided between posts, beams and braces of a structure or braces serving as variable stiffness elements and interconnecting a frame body and the variable stiffness element or the variable stiffness elements themselves. Not only the unreasonance property, but also the damping property of the structure are compositely judged by a computer on the basis of information obtained from sensors with respect to disturbances such as earthquake and wind to control the connecting condition of the variable damping device, whereby both the unresonance property and the damping property are controlled to reduce the response amount of the structure. Otherwise, the variable damping device is controlled by the judgement of only the damping property.

    摘要： A positive vibration suppression apparatus is disclosed, which suppresses vibrations of a building caused by earthquakes or winds by applying a control force to the building. The apparatus comprises a weight provided on the top of the building in a suspended form to reduce friction and an actuator provided between the weight and the building. The vibration suppression apparatus is controlled through sensing of the vibrations of the building and weight by a sensor, whereas for excessive vibrations of the building the vibrations of the weight are made close to the vibrations of the building to protect the apparatus, because the capacity of the vibration suppression apparatus is limited. Further, in an oil hydraulic system for obtaining a great control force, small and large size oil hydraulic pumps connected to respective small and large size electric motors and an accumulator are provided in parallel, so that the apparatus is warmed up at all time for oil hydraulic control with low power consumption. Two or more vibration suppression apparatuses are controlled at the same time according to the shape of the building to cope with torsional and secondary vibration components.

    摘要： An anti-earthquake bearing apparatus for bearing the weight of a structure and reducing the vibration energy propagating to the structure by using bearing bodies disposed between the structure and a foundation or another structure has spherical bag-like bearing bodies serving as said bearing bodies formed by sealing a fluid, rubber-like solid or gas into bags constituted by a rubber-sheet material reinforced with fiber. Each bag-like bearing body is provided with charging/discharging ports. Recesses for preventing positional shift of said bag-like bearing bodies are formed on the bottom surface of the structure and on the upper surface of the foundation.

    摘要： A safety monitoring device is provided for the use in an active seismic response and wind control system for exerting a control force, which restrains the vibration of a structure due to disturbances such as earthquake and wind, from an actuator in response to the above vibration. The safety monitoring device measures the work done of a seismic response control force and judges the work done of the seismic response control force to be positive or negative, so that whether or not the seismic response control is properly carried out by the actuator is judged. If any abnormality is found, a stop signal or the like is generated to stop the seismic response and wind control system, whereby the safety of the structure is ensured.

    摘要： A combination active and passive mass damping device to attenuate vibrations in a structure caused by seismic and/or wind forces. A mass is actively rendered vibratable by a hydraulic actuator and passively vibratable by use of springs. The device normally functions as an active mass damper, but, in the event of a power failure, is automatically converted by a failsafe means into a passive mass damping mode.
