    Using CFST (concrete filled steel tubes) for the arch ribs of an arch bridge is rational since CFST is resistant to axial compressive forces. The infilled concrete delays local buckling of the steel tube and the steel tube reinforces the concrete's resistance to tension, bending moments, and shear forces [1,2].The steel tube .

    Spiralwelded steel tubes (SWTs) are fabricated by helically bending a steel plate and welding the resulting abutting edges. These tubes enable larger diameters, longer jointless lengths, smaller dimensional tolerances, and more costeffective construction compared to other types of steel tubes. Notwithstanding this, the use of SWTs for concretefilled steel tubes (CFSTs) has been rather limited.
