Title:
Pin junction formal double steel pipe compression buckling restricted structure material
Document Type and Number:
Japanese Patent JP5993951
Kind Code:
B2
Abstract:
A pin joint type structural member, made of double steel pipe consisting of a main pipe and a stiffening pipe, restrains buckling so as to be stable under axial compressive force. A clearance between the stiffening pipe 2 and the reinforcing member is determined so that a ratio (Pc2/Pc2) of the reinforcing member contact force with the stiffening pipe inner surface at the end 4b of a counter-clevis side, to the reinforcing member contact force with the stiffening pipe inner surface at the end 4a of the clevis side may be 0.40 to 0.65 when the reinforcing member 4 inclines to the main pipe 1 due to the axial force acting on the main pipe 1. In addition, a length Lin that the stiffening pipe 2 overlaps with the reinforcing member 4 is at least 1.1 times as large as the reinforcing member outer diameter at the overlapping portion.
