Seismic Performance of Sliding Type Isolation with Variable Friction

The seismic response of shear type multi storey building isolated with variable friction pendulum system (VFPS) is investigated under horizontal component of near fault ground motion motions and artificial accelarogram. The VFPS, an advanced sliding type isolator, is proposed as an alternative for FPS. The governing equation of motion of building isolated with VFPS are derived and solved in the incremental form by using Newmark's (step-by-step) Beta method assuming linear variation of acceleration of the VFPS over small time interval, as the force-deformation behaviour of the VFPS is non-linear. To verify the effectiveness of VFPS, seismic performance of friction pendulum system (FPS) is compared with the same building isolated by FPS. Citation: M. J. Chauhan, D. P. Soni.
