Abstract：Base on Code For Seismic Design of Buildings（GB50011-2001）and Technical Specification for Rubber Isolation Bearing（CECS 126：2001）,the correction coefficient formulas is presented by being theoretically analyzed when equivalent lateral analysis methods is adopted. It’s pointed out that the controlling factors of correction coefficient include mass ratio between the tower and the main structure, story stiffness between the isolation layer and the tower. An correction coefficient table is supplied for design according to Technical Specification For Concrete Structure of Tall Building（JGJ3-2002）.Mode superposition method based on finite element model is used to compute seismic effects, the correction coefficient table is presented. The result is supplied for practical design by analysis.
