Summary:PROBLEM TO BE SOLVED: To provide a columnar structure which can be efficiently constructed in a short construction period by assembling a downsized segment, and can be easily repaired by suppressing heavy damage caused by an earthquake. SOLUTION: This columnar structure comprises a plurality of steel tubular bodies 11 which are vertically raised in a state of being close to one another, and a concrete section 12 which is formed in such a manner as to closely adhere to outside surfaces of the steel tubular bodies and which makes the plurality of steel tubular bodies integrally connected to one another. A plurality of segments S are heaped upward, horizontally arranged, and formed in an integrally connected shape. In the segment, precast concrete 12a which forms the outer peripheral surface of the columnar structure 1 is formed on the outside surface of a steel frame member 21 which is formed in a predetermined height-direction dimension in such a manner as to closely adhere to the outside surface of the steel frame member. A tendon is arranged inside the steel frame member, and compressive stress is introduced into the jointing surface of the steel frame member. COPYRIGHT: (C)2007,JPO&INPIT
