WebTriple friction pendulum bearing can’t be modeled directly in sap2000 software, but single friction pendulum bearing could be modeled by this software. As mentioned in the proposed model of Fenz and Constantinou (Fenz & Constantinou, 2008), triple FP bearing could be simulated based on three single FP bearings. WebA friction pendulum bearing is a partial case of a pendulum. The operating principle of a pendulum slide bearing is illustrated in Fig. 1. A swivel slider oscillates around the center of curvature of a concave spherical surface whose radius R is equivalent to the pendulum length. The oscillation period of an FPB is determined by the formula where g
