Design method of joint structure between columns and joint structure between columns

摘要

PROBLEM TO BE SOLVED: To provide a design method for a structure for joining columns together, which can suppress out-of-plane buckling without having a corner part provided with a rib, and a structure for joining the columns together.SOLUTION: In a structure for joining columns together, ribs 51 and 52 are provided to protrude in a horizontal direction from each inner peripheral surface of a steel pile 50, in a part except a corner part, in upper and lower vertical parts of the steel pipe 50. The protrusion length of the rib 51 from the inner peripheral surface is set to satisfy conditional expressions (1)-(5).SELECTED DRAWING: Figure 2
