Analysis of Fabricated Tubular Columns

Lateral buckling of submarine pipelines under high temperature and high pressure—A literature review

“…The results also indicated a diminishing influence of residual stresses on the column capacity with an increasing column slenderness. Meanwhile, it is accepted that the influence of lateral geometric imperfections dominates the influence of residual stresses when it comes to the axial buckling capacity of conventionally fabricated tubular columns (Bjoerhovde, 1973;Toma and Chen, 1979). This phenomenon has been also observed throughout the analysis of a damaged pipe under pure bending, accounting for both residual stresses and initial imperfections (Cai, 2018).…”

“…For tubes manufactured by means of rolling or welding methods, the effect is relatively small (Galambos, 1998), whereas the effect is greater for offshore pipelines obtained through mill fabrication processes. Toma and Chen (1979) estimated that residual stresses could reduce the buckling capacity of long tubular columns fabricated in such a way by about 2-4%. This effect was shown to decrease with the increase of the pipeline length (McCarron, 2018).…”
