PROBLEM TO BE SOLVED: To transmit axial force, bending moment, horizontal force, etc., burdened by a CFT column having ground structure effectively to an SRC-structure underground wall when a footing beam can be installed only in one direction. ;SOLUTION: A plurality of vertical steel framed members 2 arranged at intervals in the longitudinal direction and vertical-horizontal reinforcements disposed in the longitudinal direction on both outsides of the steel framed members 2 are installed to an SRC-structure underground wall 1, and tubular iron plates 4 in required height in size, in which a plurality of the steel framed members 2 and the vertical-horizontal reinforcements can be wrapped externally, are mounted while surrounding the steel framed members 2 and the vertical- horizontal reinforcements in the vicinity of a ground surface section. Concrete to be beforehand placed is placed in the underground wall lower than the tubular iron plates 4, FT columns 6 are built on the top end of concrete to be beforehand placed in the tubular iron plates 4, concrete to be afterwards placed is placed into the tubular iron plates 4 surrounding the CFT columns 6, and the SRC-structure underground wall 1 and the CFT columns 6 are firmly unified structurally.;COPYRIGHT: (C)1997,JPO
