SEISMIC ISOLATION OF BRIDGE SPANS BY PENDULUM SUSPENSION

In this report, the authors propose a pendulum based seismic isolation system. The results of a shake table test of a single simple pendulum span are presented. Response under varying hanger lengths, amount of damping and magnitude of impact are reviewed. The report investigates the potential impact between the span and its supports as a means of preventing a resonant response. Additionally, the report looks to minimize the displacements and rotations that are observed during an earthquake.
