Mathematical Formulation of Friction Pendulum System With Multiple Sliding Interfaces
Journal Title: Romanian Journal of Acoustics and Vibration - Year 2011, Vol 8, Issue 1
Abstract
The use of base isolation in developed countries has been recognized as a very effective method for upgrading the seismic resistance of the structures. The reduction in earthquake forces on a structure is achieved by adding horizontal soft isolation elements between the superstructure and the foundation. The efficiency of the isolator in reducing the seismic energy imparted to a structure is dependent on the flexibility of the supporting soil. The effects of radiation damping and the flexibility of the soil media are the deciding factors for structural design against earthquakes. In order to upgrade the seismic resistibility of structures and enhance the functionality of an isolator, a new base isolator called the multiple friction pendulum system (MFPS) is proposed in this study.
