STRUCTURE FOR COLUMN-BEAM JOINT PART

摘要

PROBLEM TO BE SOLVED: To provide a structure for a column-beam joint part, allowing the column-beam joining part to be tightened by enabling stress from shape steel for a beam to be reliably transferred to the whole of an SRC column (a CFT column) and preventing the stress from being concentrated only on the joint part between the shape steel for a column and the shape steel for the beam. SOLUTION: A flange 5a of a joining metallic material 5 joined to a flange 3a (one edge on one side of the square steel tube of the CFT column) on one side of the shape steel 3 for the SRC column 2 is joined to the flange 3a (one edge on the other side of the square steel tube) on the other side of the shape steel 3 by a long high-strength bolt 7 (a PC steel bar and a high-strength threaded bar). Additionally, the stress transferred from the shape steel 4 for the beam through the metallic material 5 is transferred into the SRC column 2 from the section contacting concrete 2a between the one-side flange 3a and the other-side flange 3a by means of the bolt 7 for the purpose of reducing the stress transferred directly from the shape steel 4 to the flange 3a of the shape steel 3 through the metallic material 5.
