ABSTRACT
Stainless-steel had the advantages of high strength, high corrosion resistance and easy welding, it was suitable for cold-formed thin-walled components in marine engineering. However, most cold-formed thin-walled steel components were single-limb, it had the defect of insufficient stiffness in the weak axis direction. To solve this problem, two stainless-steel lipped channels were spliced into a rectangular tube through plug welds, and an efficient cold-formed thin-walled rectangular stainless-steel spliced tubular columns was proposed. By means of splicing, the singly-symmetric cross-sections such as lipped channel sections could be transformed into doubly-symmetric cross-sections, significantly improving the axial compression performance and bending performance of the members. Three series of axial compression short column tests were carried out. The results showed that both the V-shaped stiffeners and the straight ribs played a full stiffening role in the axial compression test. Compared with the RHS-1 series components, the capacity of the RHS-2 series increased by 46.15%, the capacity of the RHS-3 series components increased by 55.38%. The finite element parameter analysis of axial compression short columns, compression-bending short columns and median long columns was carried out. The results showed that for axial compression short columns, V-shaped stiffeners and the width-thickness ratio had a great influence on failure modes. When the depth of the V-shaped stiffener was 32 mm and the angle was 90°, the section performance was optimal. When the slenderness ratio was in the range of 33.55-147.56, the overall buckling failure occurred. For compression-bending short columns and median long columns, the eccentricity ratio and the slenderness ratio had a great influence on failure modes. When the eccentricity ratio increased from 0.1 to 2.0, the ultimate compression-bending capacity decreased by 72.14% and 69.01% respectively. When the slenderness ratio was in the range of 14.81-98.73, the compression-bending stability capacity decreased significantly with the increase of the slenderness ratio. A modified calculation formula for the compression-bending capacity was proposed, with high accuracy.
