Recently, low friction elastic sliding bearings are installed seismic isolated buildings with rubber bearings and dampers. Low friction elastic sliding bearings enable the base isolation system with longer natural period than the buildings with rubber bearings and dampers. A method to predict the response of this type of structures based energy balance theory is introduced in this paper. Natural period should be estimated energy spectrum and maximum deformation in consideration of effect of energy absorption and residual deformation. A design methodology of seismic isolated buildings with low friction elastic sliding bearings, that is based an energy balance, is presented.
