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: Further results on the frictional properties of Teflon-steel interfaces in sliding bearings are reported. Values of the breakaway (static) and sliding coefficients of friction of woven Teflon in contact with polished ...

Abstract: A shake‐table study of the friction‐pendulum isolation system, installed in a six‐story, quarter‐scale, 52‐kip model structure, is presented. Two bearing materials are studied, one with a peak friction coefficient of 0.075 ...
