Abstract

Essential steel components with variable cross-section are fabricated from welded plates, which are primarily employed for the growth of the construction industry in beams according to the stress and stiffness requirements of the structure. Lateral-torsional buckling, in which the beam experiences non-uniform twisting and buckling about its weaker axis, is one of the most common failure modes. This dissertation focuses primarily on the lateral-torsional buckle of non-prismatic I-beams. The development of differential equations for deformation analysis of the non-prismatic beam. ANSYS results and deformation equation results are compared to validate the methodology. Using ANSYS, the lateral torsional buckling of a non-prismatic I-beam section with uniformly distributed load is analyzed. In finite element analyses, the solid element approach is used to determine the lateral buckling load for various cross-sections (β = 0.1 to 1.0) by analyzing their behavior. In addition, a stiffener is used to prevent lateral buckling, and the results are compared to a model without stiffeners.

用有限元法研究非棱柱工字钢的横向扭转屈曲

可变截面的基本钢构件由焊接板制成，根据结构的应力和刚度要求，焊接板主要用于梁中建筑行业的发展。横向扭转屈曲是最常见的失效模式之一，梁在其较弱的轴上经历非均匀扭转和屈曲。本文主要研究非棱柱形工字梁的横向扭转屈曲问题。非棱柱梁变形分析微分方程的发展。将ANSYS结果与变形方程结果进行了比较，验证了该方法的有效性。利用有限元分析软件ANSYS，对均匀分布荷载作用下非棱柱形工字钢截面的横向扭转屈曲进行了分析。在有限元分析中，实体单元法用于通过分析不同横截面（β=0.1至1.0）的行为来确定其横向屈曲载荷。此外，还使用了加劲肋来防止横向屈曲，并将结果与没有加劲肋的模型进行了比较。
