Prepared by the Highway Innovative Technology Evaluation Center (HITEC), a CERF Service Center. This report summarizes the results of a detailedØevaluation of Friction Pendulum Bearings,Ømanufactured by Earthquake Protection Systems, Inc. The report is part of a program to test the performance of 11 seismic isolators and dampers produced by several manufacturers. The devicesØwere tested for stability, response during earthquake simulations, and fatigue and weathering effects.

Presents the results of a detailed evaluation for one technology out of eleven that were evaluated. The evaluations were designed to test the performance of seismic isolators and dampers produced by several manufacturers.
