Earthquake Isolation Bearing for Bridges Using Shape Memory Alloy

摘要

The present invention relates to a seismic isolation device for bridges using a shape memory alloy that does not have residual deformation in response to an earthquake load and has an excellent energy dissipation capacity. In addition, a seismic isolation means including a shape memory alloy rod or a plate is further attached around the bearing, and the upper and lower plates and the connection of the seismic isolation means have at least one end portion formed as a fixed portion, and the displacement of the seismic isolation device in the vertical direction or The other end is formed at the free end so as not to restrain the deformation.;Bridge device, shape memory alloy, shape memory effect, base isolation device
