ST7-1.40.35.11 Modelling Friction Pendulum Seismic Isolation Bearings
Friction Pendulums seismic isolators are used for isolating earthquake movements from the buildings they support, thus protecting the buildings from earthquake damage. These bearings also dissipate energy associated with relative movement between the building and the ground by their hysteretic behaviour. Typical response of a single isolator is schematically illustrated on the right where FL and DL are the lateral force and displacement, respectively. The stiffness associated with slippage (step...
