Seismic isolation assembly

摘要

A seismic isolation assembly is defined by a first support plate and a second support plate disposed in parallel relation with a spacing being provided between the support plates. The first support plate is connected to ground and the second support plate is attached to a structure to be isolated. A set of wire rope isolators are disposed between the first and second support plates as well as at least one linear damper that is angularly disposed and mounted between the first and second support plates.

1. A seismic isolation assembly comprising:
a first support plate configured for fixed attachment to a base; a second support plate disposed in parallel and substantially centered relation with the first support plate and configured for fixed attachment to a structure and in which a spacing is defined between the first and second support plates; a plurality of wire rope isolators fixedly mounted in spaced relation between the first support plate and the second support plate, each wire rope isolator having an upper mounting block, a lower mounting block, and a plurality of wire coils introduced through lateral holes formed in each of the upper and lower mounting blocks, each wire rope isolator further having a primary axis disposed along a major dimension of the first and second support plates; and a plurality of sets of linear dampers, each linear damper including a first end attached to an upper surface of the first support plate and an opposing second end attached to the second support plate, and in which each set of linear dampers is disposed between adjacently spaced wire rope isolators, with each linear damper being mounted at an acute angle between the first and second support plates relative to a plane of said support plates.
