(1) Its node connection is suitable for direct welding, which does not need to pass through the gusset plate or other connectors, which saves labor and materials.
(2) When necessary, concrete can also be poured into the tube to form a composite member.
(3) The geometric characteristics of the pipe section are good, the pipe wall is generally thin, the section material is distributed around the centroid, the section radius of gyration is large, and it has strong torsional stiffness; as a compression, compression bending, and two-way bending member, its The bearing capacity is higher, and the straightness and section size accuracy of cold-formed pipes are better than those of hot-rolled open sections.
(4) The appearance is more beautiful, especially the pipe truss composed of steel pipe members, without redundant node connections, and has a strong sense of modernity.
(5) In terms of anti-hydrodynamic properties, the cross-section of the circular tube is better, and the effect of wind and water flow is greatly reduced. Rectangular tube sections are similar in this respect to other open sections.
(6) The
large-diameter steel pipe is a closed section; when the average thickness and cross-sectional area are the same, its exposed surface area is about 50% to 60% of the open section, which is beneficial to anti-corrosion and can save coating materials.
