A negative stiffness device and method for seismic protection of a structure is described. In one embodiment, the device has an anchor frame and a movement frame laterally translatable relative to the anchor frame. The anchor frame and movement frame have respective extension portions. A linkage is pivotably connected to the extension portion of the anchor frame. A compressed spring has a first end is attached to the extension portion of the movement frame and a second end attached to the linkage. The compressed spring has a spring force.

Seismic protection materials are derived from assemblages of unit cells, where each of the cells has a core, one or more shells disposed about the core, and rigid plates bounding the shells. The cores limit relative vertical movement between the plates, and the shell(s) limit relative lateral motion between the plates. Uncompressed cores are preferably substantially spherical or cylindrical, and can be solid or hollow. Unit cells can be aligned in same or different directions, both within a given layer of cells, and in different layers of cells. Assemblages can have any suitable overall shape and size, depending upon application, and for example can support objects ranging from table top equipment to large buildings and bridges.
