METHOD FOR CHANGING HORIZONTAL RIGIDITY OF BASE ISOLATION MEMBER FOR SUPPORTING BUILDING

摘要

PROBLEM TO BE SOLVED: To provide a method for changing horizontal rigidity of a base isolation member for supporting an existing building requiring application change.SOLUTION: In a method for changing horizontal rigidity of a base isolation member for supporting a building, some of a plurality of existing base isolation members 14 provided in a lower structure 12 to support an upper building 13 are replaced with new base isolation members 16 and 18 different in shear rigidity from the existing base isolation member 14 to change horizontal rigidity of an existing base-isolated building 10.
