“…The residual stresses were applied to the FEA models using the *INITIAL CONDITION command in the FE program. Figure (2) show the distribution of longitudinal residual stress, measured on steel beams using the sectioning method, and the measured values of each section were used in the FEA models Yang et al [25]. By partitioning the web and flanges of the cross-section, residual stresses were introduced into the FEA models.…”

“…The critical load for the lateral-torsional buckling depends on the material properties, crosssectional geometry, non-braced length, end restraint conditions, and type of loading. Furthermore, as presented by El-Mahdy and El-Saadawy [2], a 3D model has been created to study the LTB in I-beams that have a cross-sections with single axis of symmetry. They considered the influence of the span length of the beam and the width of the flange of the cross-sections on the resistance results.…”

“…Lateral-torsional buckling theory is covered extensively in text books ( [2][3][4][5]) and a considerably large number of analytical and experimental research articles have been published on this topic. Noticeable contributions have been provided by Eishakoff, with reference to the response of variable cross-section beams ( [6]); El-Mahdy, for what concerns the inelastic lateral-torsional buckling of singly symmetric I-beams with variable flange ratio ( [7]); and Scott, regarding an experimental investigation on the natural frequencies and mode shapes of tapered C-beams ( [8]). Several approaches can be employed for solving the stability problem of C-beams with variable cross-section.…”

“…Дуже [33] і [34]. Так в [33] проаналізовано НДС двотаврової балки зі змінною шириною пояску на дію згину з крученням застосовуючи оболонкову скінченно-елементну модель з врахуванням геометричної і фізичної нелінійностей, при роботі в пружній та пружно-пластичній областях. В публікації [34] запропонована модель розрахунку непризматичної тонкостінної конусоподібної балки відкритого профілю, довільного поперечного перерізу, де результати були перевірені з використанням оболонкових скінченних елементів.…”
