Abstract: Modelling techniques of Double Concave Friction Pendulum (DCFP) system are presented. Seismic responses of the three-dimensional single-story building isolated by DCFP with different coefficient of friction and initial time period of top and bottom sliding surfaces are investigated under triaxial ground excitations and compared with unilateral and bilateral ground excitations. The influence of vertical flexibility on horizontal response is investigated. It is observed that the triaxial ground motion has noticeable effect on response of the building relative to unilateral ground motion. The error in peak resultant absolute deck acceleration and the error in peak resultant isolator deformation, occurring by neglecting vertical ground motion component, could be significant.
