Abstract

PURPOSE:To control the bearing destruction of a column concrete by welding an upper vertical steel pipe member to an upper flange of a horizontal steel frame member and, welding a lower vertical steel pipe member to a lower flange of the horizontal steel frame member. CONSTITUTION:An upper vertical steel pipe member 4a buried in an upper reinforced concrete column of a joint section is welded vertically to an upper flange 1a of the longitudinal center section of a horizontal steel frame member 1 formed of an H-shaped steelmaterial. A lower vertical steel pipe member 4b buried in a lower reinforced concrete column of the joint section is welded vertically to a lower flange 1b of the longitudinal center section of the horizontal steel frame member 1. According to the constitution, bending stress generated in the column is borne by both steel pipe members 4a and 4b, and the bearing destruction of the column concrete in part coming into contact with the faces of the flanges 1a and 1b can be inhibited.
