ABSTRACT:
A storage rack system to be installed on a floor has a plurality of columns, is more flexible in a down aisle dimension than it is in a cross aisle dimension, and has at least a first column and a second column adjacent one another in the cross aisle dimension. A storage rack vibration isolator for use with this storage rack system comprises at least one seismic vibration absorption and dissipation structure constructed to be located primarily between the first and second columns to reduce the storage rack system's natural frequency in at least the cross aisle dimension. The seismic vibration absorption and dissipation structure includes a first member connectable to the storage rack system and a second member connectable to the floor. At least one column support assembly is mountable to at least the first and second columns to enable them to move with respect to the floor. A structure limits the movement of the first and second columns to substantially the cross aisle dimension.
