An analysis of the torsional seismic response for a single?axis eccentric multistory frame buildings with base-isolation is presented. The equations of motion of the torsional response for multistory frame isolated structure under earthquake action are given. The seismic responses of the structural model under different eccentricity both with or without base isolation were calculated. The results indicate that the base isolation will decrease the torsional responses of the system significantly.
