“…This disparity raises concern over the structural adequacy of real columns in relation to the design strengths provided by the Standards (Bild and Trahair 1989). However, in essence, the formulation of modern column curves is based on fitting a design model to available laboratory test results for real columns, and performing statistical analyses to determine suitable resistance factors to achieve lower bound predictions or the required level of reliability.…”

Complementary to recent studies on the cross-section behavior of elliptical hollow sections, investigations into the member response have also been performed and described in this paper. The first stage of these investigations involved a series of precise column buckling tests on hot-finished steel elliptical hollow sections. In total, 24 flexural buckling tests about the minor and major axes were carried out. Specimen sizes and lengths were carefully chosen in order to cover a wide range of both cross-section and member slendernesses. The non-dimensional column slenderness of the test specimens varied between 0.19 and 1.58. Measurements were taken of specimen geometry, global initial geometric imperfections and tensile material properties. Key results from the tests including the full load-deformation histories have been presented and discussed. The test results have also been supplemented by 158 numerically generated results, allowing a wider range of geometries to be investigated. Design rules for the member buckling resistance of elliptical hollow section columns have been proposed and verified by means of reliability analysis. The presented results are the first member buckling tests on elliptical hollow sections, and represent part of the development of comprehensive structural design rules for these sections.2

“…Compared to sections free of residual stresses, the magnitude and distribution of these compressive residual stresses influences the strength of compression members because of the earlier initiation of yielding and subsequent lowering of flexural strength that occurs. The effects of residual stresses are more severe for I-section columns bent about the minor axis than the major axis [Bild and Trahair, 1989].…”

“…The value of this imperfection used in the generation of the axial compressive strength curves by European design specification -EN 1993-1-1:2005 -is bellow the tolerance values prescribed by the manufacturing specifications (CEN, 2005;Beedle, 1991;Galambos, 1998). This difference awakes a concern about the actual value of the member's strength when compared to that evaluated according the design specification (Bild & Trahair, 1989).…”

In this paper, a simple formulation for current application for the axial compressive strength determination of hot rolled circular hollow steel sections, with sinusoidal form initial crookedness and values of the central deflection between 1/2,000 and 1/500 of the length, is proposed. In order to validate the analysis, several numerical models were generated by finite element method, considering members with 1/1,000 of the length initial crookedness, and the results were compared with the values obtained by EN 1993-1-1:2005. Using the methodology of modeling validated, many other members with initial crookedness of 1/2,000, 1/1,500, 1/750 e 1/500 of the length were analyzed, allowing to obtain the values of the reduction factor, , as a function of the reduced slenderness parameter, ̅. The values of  of members with initial crookedness between these two limits were evaluated by polynomial interpolation.
