Abstract
A seismic isolation device comprises an isolation support and an inerter unit arranged on the side of the isolation support, the isolation support having an upper plate and a lower plate, the inerter unit having a rotating rod extending to the side of the lower plate and a flywheel linked with the rotating rod, wherein when the upper and lower plates of the present invention undergo relative displacement due to the occurrence of an earthquake, the inerter unit provide an inertance to reduce the displacement reaction, thereby providing better seismic isolation effect.
Claims13
A seismic isolation device comprising:
- an isolation support, comprising an upper plate, a lower plate, and at least one roller located between the upper plate and the lower plate, wherein the lower plate comprises an upper surface with a lower reset ditch, and the upper plate comprises a lower surface with an upper reset ditch corresponding to the lower reset ditch, wherein the at least one roller is located between the upper reset ditch and the lower reset ditch;
- and
- an inerter unit, comprising a rotating rod and a flywheel, wherein the rotating rod is arranged on a side of the upper plate and has an upper end and a lower end, wherein the lower end of the rotating rod extends to a side of the lower plate, and the upper end of the rotating rod is linked with the flywheel, and
- wherein the inerter unit provides an inertance to reduce a displacement reaction resulting from relative displacement between the upper plate and the lower plate.
