【Abstract】 Reasonable design about displacement and damping ratio of base-isolated story was studied in this paper for seismic isolation design.The theoretical formula for damping ratio of lead rubber bearing was proposed,and the ideology of base-isolated-story design via earthquake fortification intensity was also introduced.Based on the national design code and specification,the corresponding formula for the displacement response was derived.Meanwhile the design method about base displacement and damping ratio of base-isolated story was investigated in this study.更多还原
