Abstract
A vibration isolating device is provided with an isolator formed by an elastic member of laminated rubber and interposed between the base of a building and its foundation, for supporting the vertical load of the building and obtaining a long period dumping. A main dumper is disposed side by side with the isolator, for effectively damping relatively strong vibrations, and a sub-damper is disposed side by side with the isolator, for effectively dumping relatively weak vibrations. The vibration isolating device damps weak vibrations by the sub-damper and strong vibrations by the main damper, and hence gets effective damping of a wide range of vibrations from slight traffic vibrations to great earthquake shocks.
