A passive damper for earthquake hazard reduction includes an inner member received in an outer member, with an elastomeric material disposed in the gaps between the inner and outer member. The elastomeric material has at least a first and a second portion. The first portion is bonded or connected to both the inner member and outer member such that no slippage occurs between the members and the material. The second portion is not bonded or connected to at least one of the inner and outer members such that slippage may occur.

A vibration damper includes a suspended mass connected to a pipeline or similar structural member by a support ring and an assembly of interconnected, generally cylindrical damper members formed of an elastomer material suitable to be stressed in shear. The damper assembly is of modular construction so that the damper can be easily tuned to particular frequency and amplitude conditions of different pipes and spans, respectively.
