ABSTRACT
Base isolation or seismic isolation enables the reduction in earthquake forces by lengthening the fundamental natural time period of structure; hence it is significantly effective in low and mid-rise buildings with less than 10 stories. Taller building with height more than 10 stories already have larger time period and the effectiveness of base isolation is reduced., In this paper an attempt has made to study the feasibility of sliding isolation at intermediate floor levels. R.C.C. 18 stories are analyzed by dividing each building into different segment and each segment is isolated with Triple Friction Pendulum isolators. The response of structure with isolators at multiple floor levels are studied with 1940 El Centro, 1979 Array#05 and 1989 Gilroy time-history and responses are compared to the conventional fixed base structure and with structures isolated at base and at intermediate floor level.
