To choose the right bearings accurately in the design of high-rise isolated structure,the method that the seismic action will be reduced to 1/3~1/2 input to high-rise seismic structure and the calculation results of vertical support reaction at the bottom of the structure will be considered as the basis of choosing bearings.To make designers easily master this method,the design process proposed by this paper will be represented by taking a pratical project for example,which is based on Etabs finite elements...
