METAL HOLLOW COLUMNAR MEMBER AND METHOD OF MANUFACTURING THE SAME

PROBLEM TO BE SOLVED: To provide a hollow columnar member hard to be buckled as a whole due to local bending even if a load with large axial load vector including diagonal load is applied thereto, capable of well absorbing the input energy under the load applied thereto. SOLUTION: This hollow column...

Zusammenfassung:PROBLEM TO BE SOLVED: To provide a hollow columnar member hard to be buckled as a whole due to local bending even if a load with large axial load vector including diagonal load is applied thereto, capable of well absorbing the input energy under the load applied thereto. SOLUTION: This hollow columnar member 1 has corner parts 2 at the four corners, respectively. One or more recessed parts 3 are formed on at least one of four sides of the member. The C value (Lmin/Lmax) obtained by multiplying the overall ridge quantity N in the cross section thereof by the ratio Lmin/Lmax of the minimum side length Lmin to the maximum side length Lmax in the cross section is 4-40.
