Abstract
The dynamic response characteristics of a slip surface isolation system having restraints which produce a bilinear hysteresis are investigated. Design issues pertaining to base isolated structures are reviewed with regard to slip surface systems. The proposed restraint mechanism results in three parameters which can be selected so as to produce the optimal behavior for a given structure. Results show that the proposed system can be effective in reducing accelerations in the structure and that it may offer certain advantages compared to other isolation devices.
