Abstract

Numerical study of multistory building with equipment isolated by the Polynomial Friction Pendulum Isolator (PFPI) is carried out. Six different earthquake ground excitations are used as input ground motions. For this purpose, seismic response of building with equipment isolated with PFPI is obtained under normal component of different ground motions by using Newmark’s linear acceleration method. The seismic response of building isolated with PFPI is compared with that of Variable Frequency Pendulum Isolator (VFPI) to examine the effectiveness of PFPI. From the comparative study, it is observed that the VFPI is more efficient in reducing the seismic response of building with equipment as compared to PFPI.
