PROBLEM TO BE SOLVED: To enhance the ductility of a wall column by adding end part reinforcing shear reinforcing bar to the both ends parts in the column height direction of the wall column cross section of a shear reinforcing bar. ;SOLUTION: End part reinforcing shear reinforcing bars 12, 12 are employed as shear reinforcing bars 3 for he intermediate part 6 as well as a single outer circumferential bar 11. The end part reinforcing shear reinforcing bars 12 are so arranged as being overlapped into two layers in the same position as the outer circumferential bar 11 adjoining thereto. The column longitudinal direction of the end part reinforcing shear reinforcing bars 12 may be arranged in the same position as the outer circumferential bar 11 or in the intermediate position of the pitch of the outer circumferential bar. Core bars may be arranged in the inside of the end part reinforcing shear reinforcing bars 12 and the inside of the both end parts in the column height direction of the wall column cross section of the outer circumferential bar 11. The wall column height end part is thus partially reinforced so as to provide the approximately same reinforcing effects as the reinforcement of the whole cross section. This constitution can enhance the ductility of the wall column.;COPYRIGHT: (C)1999,JPO
