Friction Pendulum Dampers for Earthquake Isolated Structural Systems
Journal Title: Romanian Journal of Acoustics and Vibration - Year 2012, Vol 9, Issue 1
Abstract
Base isolation systems have become a significant element of a structural system to enhance reliability during an earthquake. One type of base isolation system is Friction Pendulum Dampers in which the superstructure is isolated from the foundation using specially designed concave surfaces and bearings to allow swayunder its own natural period during the seismic events. Friction Pendulum Dampers are seismic isolation bearings that have been as a means of bridge, and building retrofit in numerous cases around the world. To assess their impact on structure performance, models are needed to capture the behavior of these highly nonlinear elements.
