COLUMN FOR LOAD RESISTANCE STRUCTURE

PROBLEM TO BE SOLVED: To improve a column's strength and toughness and to achieve the recycling and reuse of the column.SOLUTION: A column for load resistance structure is provided with a hollow column body 11, noncompressible filling granular materials 30 packed in the column body 11, a plug lid 20 installed in the end opening of the column body 11 to be slidable and for closing the end opening and pressing the filling granular materials 30, and a tension member 40 of which end is fixed to the plug lid 20 and that applies pressure force to the filling granular materials 30 through the plug lid 20. The column forms a composite structure by integrating a hard lump 31 formed by tensioning the tension member 40 and compacting the filling granular materials 30 with the column body 11 restraining the hard lump 31.
