DYNAMIC ANALYSIS OF FRICTION PENDULUM BASE ISOLATED STRUCTURES C0NSIDERING SOIL-STRUCTURE INTERACTION

the satisfactory performance of friction - pendulum system during earth quake leads to growing demand for both research and construction to involve soil structure interaction in the analysis of friction pendulum base isolated structure stiffness and damping of soil medium should be transformed from frequency domain parameters in to time domain parameters on account of severe nonlinearity of friction -pendulum system during earhquake.
