PROBLEM TO BE SOLVED: To provide the perpendicular structural member of a building such as a column, a wall or the like which can maintain PC steel and a reinforcing bar within the range of linear restoring force and prevent cracks and damage even when it undergoes impactive tensile force and bending moment caused by a major earthquake and strong wind. SOLUTION: The building is constructed by using the perpendicular structural member, and vibration control PC steel materials 18, 16 are inserted into and arranged in the interior of a cross-sectional nucleus 10a and on the outside of the cross-sectional nucleus of the cross section of the perpendicular structural member constructed on each floor level from the foundation of the building to the top floor level. Then at least the vibration control PC steel materials 18 arranged in the cross-sectional nucleus 10a are arranged from the foundation to the top floor level in a continuous state through its length, and different tension-introducing forces are exerted on different PC steel materials 18, 16 arranged in the interior of the cross-sectional nucleus 10a and on the outside of the cross-sectional nucleus, and tension fixation is performed. Then the cross-sectional yield strength of the perpendicular structural member is increased, and the degree of a safety allowance for a member at the time of an earthquake is significantly increased by increasing the cross-sectional yield strength of the perpendicular structural member. Thus, vibration control damper performance by the effect of the vibration control horizontal force Pr is exerted. COPYRIGHT: (C)2011,JPO&INPIT
