摘要

摘要: 与简单卷边相比，复杂卷边因在限制板件屈曲、提高局部稳定性方面具有更加优越的性能，在截面设计中得到大量应用。然而，大多数关于复杂卷边的研究都是定性的。为此，通过对均匀受压翼缘板件屈曲性能的研究，基于屈曲半波长和屈曲系数的判断原则，提出了翼缘板件的复杂卷边尺寸限值及配置形式。卷边最小尺寸限值基于卷边刚度是否大于加劲最小刚度以及屈曲半波长是否小于翼缘板件宽度的原则考虑，卷边最大尺寸限值基于均匀受压翼缘板件是否先于卷边板件发生屈曲的原则以及经济性考虑。利用有限条法对比分析中、美两国规范关于简单卷边的规定，确定了翼缘板件的卷边限值，即最小限值满足屈曲半波长等于翼缘板件宽度或屈曲系数大于4.24，最大限值不超过翼缘板件宽度；对复杂卷边进行参数化分析，给出了复杂卷边高厚比限值的设计表格与计算公式；利用优化算法，在考虑经济性与受力性能的条件下，给出了冷弯均匀受压翼缘板件卷边设计的建议及最佳复杂卷边尺寸。

Abstract: Compared with simple edge stiffeners， complex edge stiffeners have been widely used in design because of their superior performance in limiting plate buckling and improving local stability. However， most research on complex edge stiffeners is qualitative. In this paper， based on the buckling performance analysis of the plate under uniform compression， the judgment principle based on the buckling half-wavelength and buckling coefficient was put forward. The limits and configuration of the complex edge stiffeners were analyzed and suggested. The minimum limit of edge stiffeners was based on the principle of whether the stiffness was greater than the minimum edge stiffness and the buckling half-wavelength was less than the width of plates. The maximum limit of the edge stiffeners was based on the principle of whether the uniformly compressed plate buckled before the stiffened plate and the economic consideration. Based on the comparison and analysis of the Chinese and American codes on simple edge stiffeners， the limits were determined：the minimum limit met the requirements that the buckling half-wavelength was equal to the width of the stiffened plate or the buckling coefficient was greater than 4.24， and the maximum limit was no more than the width of the stiffened plate. Based on the parametric analysis of the complex edge stiffeners， the design table and calculation formula of the limits of height-thickness ratios were obtained. Based on the optimization algorithm， the suggestions and the optimum size of complex edge stiffeners of cold-formed uniformly compressed plates were obtained with consideration of economy and mechanics.
