PROBLEM TO BE SOLVED: To obtain a rational structure adaptable for a high-rise building or an extremely high-rise building. SOLUTION: The high-rise building or an extremely high-rise building has a tubular structure forming a chief frame composed of an outer peripheral tube frame 1 provided at the outer periphery and a core tube frame 2 provided at the center. The core tube frame is formed of a rigid frame of a reinforced concrete core column 10 and a core beam 11 in the apex of the building, and the other part except the apex is made of a reinforced concrete high rigid core wall 9 . The core wall constituting the core tube frame except the apex is formed into peripherally divided cylindrical shapes and in the divided part of the core wall, boundary beams 12 functioning as vibration proof dampers are provided on respective layers.
