<p><P>PROBLEM TO BE SOLVED: To provide a structure made of reinforced concrete with high toughness that can impart high deforming performance to reinforced concrete by suppressing buckling of axial reinforcing bars and also increase concrete filling properties by reducing the amounts of hoops and intermediate hoops. <P>SOLUTION: A precast form 7 having hoops 11 buried inside is buried nearby a lower end of a columnar body 3 made of reinforced concrete. The precast form 7 is higher in compression strength than an outer edge concrete part 9 which is concrete constituting the columnar body 3 and adjacent in the axial direction of the precast form 7. Compression force equal to or larger than the compression strength of the outer edge concrete part 9 is prevented from being applied to the precast form 7. Consequently, buckling deformation of axial reinforcing bars 13 in the columnar body 3 can be prevented with the rigidity of the precast form 7. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
