ABSTRACT:
A composite seismic isolator for a structure having a column or wall to be supported on a foundation comprising first and second seismic isolators having vertical axes. The first seismic isolator is constructed so that it is relatively soft in a horizontal direction transverse to the vertical axis in comparison to the second seismic isolator. A restraint is provided by the second seismic isolator for restraining transverse movement of the first seismic isolator between predetermined limits. The composite seismic isolator is mounted between the foundation and the wall or column to be supported by the foundation.
