<P>PROBLEM TO BE SOLVED: To provide a structure vibration control and base isolation method with which a load on a lower structure caused by application of a great inertia force acting on an upper structure during an earthquake can be reduced by transmitting the inertia force which acts on the lower structure during the earthquake, to the upper structure after reducing and damping the inertia force, and reducing horizontal displacement of the upper structure. <P>SOLUTION: According to a structure vibration control and base isolation method, between an upper structure 3 and a lower structure 2 of a structure such as a construction or a bridge, a vibration control and base isolation system 1 is disposed which is comprised of a horizontal force generation mechanism 100 generating a horizontal force in a reverse direction to an inertia force acting on the lower structure during an earthquake and a rubber-based elastic body 5 connected to the horizontal force generation mechanism. In the case of an earthquake, the horizontal force generation mechanism converts the inertia force acting on the lower structure into the horizontal force in the reverse direction and the rubber-based elastic body is deformed in a reverse direction to an inertia force direction in the lower structure, thereby reducing earthquake energy to be transmitted to the upper structure and reducing horizontal displacement amounts of the upper structure and the lower structure. <P>COPYRIGHT: (C)2013,JPO&INPIT |
