PROBLEM TO BE SOLVED: To provide a column-beam connection structure that avoids an impact of strength impairment at a welded part of a through-diaphragm, at the same time avoiding high heat input welding of an inner diaphragm or mitigating an impact thereof, reducing a total volume of welding, and improving plastic deformation performance of the column.SOLUTION: A column-beam connection structure includes a first skin plate 16, diaphragms 20a, 20b, and a second skin plate 18. Front and rear sides of the first skin plate 16 comprise a general part 16a, an inclined part 16b, and a widened part 16c. Front and rear sides of the diaphragms 20a, 20b are positioned at an edge part of the widened part 16c. The second skin plate 18 is disposed above and below the diaphragms 20a, 20b disposed between two first skin plates 16. Right and left sides of the second skin plate is connected by welding on the first skin plate 16, while upper and lower sides thereof are connected by welding on an undersurface or a top surface of the diaphragms 20a, 20b.SELECTED DRAWING: Figure 1 |
