摘要： PROBLEM TO BE SOLVED: To solve a problem that a damping function is abruptly decreased at a certain deformed state in a structure in which a restrictive structure against deformation like a brake or a stopper is complementarily assembled because a larger relative deformation (stroke) than the main vibration system arises in the mass damper, in conventional mass damper system in which an additional mass is light in comparison with the weight of building SOLUTION: A multi-stage laminated rubber 3 is superposed on the upper face 1a of a building to support a movable mass 2 and an extensible cylinder type oil damper 4 bringing out a resistant force in the axial direction is connected so as to freely shake the head in the horizontal transfer direction and stand straight on the stationary condition between the bottom face 2a of the movable mass 2 and the upper face 1a of the building. And the mass damper is designed to function so that the attenuating force of the mass damper increases nonlinearly and continuously in accordance with the increase of the response deformation χ of the mass damper.

摘要： PURPOSE:To provide a vibration control method and its device for a structure to be installed at a low cost and in a small space, and capable of highly reliable vibration control. CONSTITUTION:Weights 12 are provided in the upper side of a structure 1 to be a vibration-control object, elastic bodies 11 are provided between the structure and the weights, and also a damping mechanism 13 capable of varying a damping coefficient is provided to control vibration of the structure while varying the damping coefficient of the damping mechanism in accordance with the vibration mode of the structure changing at all times. In setting the damping coefficient of the damping mechanism, when the structure is vibrated, a dominant vibration mode and a vibration level are determined from the vibration response data of the structure to determine the damping coefficient of the damping mechanism suitable for the vibration mode from a determined value to set the damping coefficient of the damping mechanism. This controls vibration of the structure.

摘要： PROBLEM TO BE SOLVED: To provide a method for controlling active base isolation, which can implement optimum vibration control according to the circumstances of an installation location and the capacity of an actuator. SOLUTION: There is employed a method for controlling the active base isolation, in which an evaluation function in optimum feedback control is determined by independently weighing the absolute acceleration and the relative displacement of a floor 2A or a building 2B. According to the method, not only both the absolute acceleration and relative displacement of the floor 2A or the building 2B can be reduced, but also it is determined which amount of the absolute acceleration and the relative displacement can be emphatically reduced.
