JOINT UNIT BETWEEN REINFORCED CONCRETE COLUMN AND STEEL FRAME BEAM

摘要

PURPOSE: To bear part of bending stress generated in a column on both vertical steel framed members by burying both up and down vertical cross shape steel frame members in the reinforced concrete column. ;CONSTITUTION: In vertical steel framed members 4a and 4b, for example, two T-shape steels are combined along the center line of a web of an I-shape steel and are welded to both faces of the web, and cross shape steel frames having flanges on the front ends of webs having a cross-shape in the cross section are formed. The lower end of the upper vertical steel framed member 4a is connected to the upper surface of a flange 1a of a horizontal steel frame member 1 to weld, and the upper end of the lower vertical steel framed member 4b is connected to the lower surface of a flange 1b of the horizontal steel frame member 1 to weld. The upper vertical steel framed member 4a and the lower vertical steel framed member 4b are buried into a reinforced concrete column 2, and the bearing destruction of a column concrete in part coming into contact with both up and down flange surfaces of the horizontal steel frame member 1 is prevented by bearing part of bending stress generated in the column on both steel frame members 4a and 4b.;COPYRIGHT: (C)1995,JPO
