PROBLEM TO BE SOLVED: To provide an independent structure for which a column does not obstruct passing or obstruct a line of sight, and a position of the column to a roof is adjustable further.SOLUTION: The independent structure includes a roof and a column, and for the roof, an inclination angle &thetas; to a horizontal plane is in the range of 0°<&thetas;≤20°, and one or more columns are arranged on a straight line orthogonal to the inclination direction of the roof. An inclination direction attaching position to the roof can be set between a position at which a bending moment acting on a column head becomes 0 to a position at which the bending moment acting on a column base becomes 0 when blow-up loads with prescribed strength act on the roof. |
