Storage rack vibration isolators and related storage rack systems

A storage rack vibration isolator for use with a storage rack system installed on a floor, the storage rack system having a plurality of columns, the storage rack system being more flexible in a first horizontal dimension and a less flexible in a second horizontal dimension, the storage rack system having at least a first column and a second columns located adjacent one another in the second horizontal dimension, said storage rack vibration isolator comprising:

• at least one elastomeric component installable primarily between the first and second adjacent columns in the second horizontal dimension to reduce the natural frequency of the storage rack system in at least the second horizontal dimension, said elastomeric component having a first member mountable to the storage rack system and a second member mountable to the floor;
• a sliding base pad attachable to the lower end of the first and second columns, said sliding base pad having a length which enables it to extend between and under at least the first and second columns;
• a fixed base pad attachable to the floor, said fixed base pad having a length which enables it to extend between and under at least the first and second columns, said sliding base pad positioned on said fixed base pad when the lower ends the first and second columns are attached to said sliding base pad such that said sliding base pad slides over said fixed base pad when the first and second columns moves during seismic events;
• and
• at least one fastening member attached to said second member and to said fixed base pad to mount said second member to the floor, said at least one fastening member enables said first member to move with the first and second columns during seismic events, said at least one fastening member mechanically restricting movement of said first and second columns to substantially the second horizontal dimension.

A storage rack system installed on a floor comprising:

• a plurality of columns mounted on at least two column support assemblies for movement with respect to the floor;
• said storage rack system having a structure that is more flexible in a first horizontal dimension and a less flexible in a second horizontal dimension;
• a first column and a second column located adjacent one another in the second horizontal dimension;
• at least one storage rack vibration isolator installed primarily between said first and second columns in the second horizontal dimension, said at least one storage rack vibration isolator comprising at least one seismic vibration absorption and dissipation structure to reduce the natural frequency of said storage rack system in at least the second horizontal dimension, said storage rack vibration isolator including a first member connected to the storage rack system and a second member connected to the floor;
• and
• at least one structure to limit the movement of said storage rack system during seismic events to substantially the second horizontal dimension.
