Abstract: A mathematical model of the factional behavior of Teflon sliding bearings for conditions of interest in base isolation is developed. The calibration of the model is based on extensive experimental data that were presented ...

Abstract: This paper describes the frictional properties of sheet type Teflon‐steel interfaces in relation to their application in sliding bearings for base‐isolated building and bridge structures. A series of laboratory experiments ...

Abstract: This paper presents an experimental and analytical study of hybrid control of bridges using sliding bearings, with recentering springs, in parallel with servohydraulic actuators. A new control algorithm with absolute ...
