摘要

针对铝合金梁中可能出现的腹板受弯屈曲，通过有限元方法研究了铝合金受弯板件的稳定性。对比了国外规范设计方法的计算结果与有限元计算结果，讨论了现有的各种方法的优点和存在的问题。根据有限元的计算结果，参考国外规范的设计方法，对我国钢结构规范中的相关设计公式进行适当修改，给出了铝板受弯屈曲的屈曲强度和屈曲后强度的计算方法。结果表明：提出的设计方法在计算铝板受弯的屈曲强度和屈曲后强度时可以得到准确而偏于安全的结果，该方法适用于铝合金受弯板件局部稳定性的设计。

Abstract

As for the local buckling of aluminum bending members

a finite element analysis of the stability of aluminum plates under bending was performed. Compared with the results of codes’ method and finite element method

the advantages and disadvantages of existing codes were discussed. Base upon the results of simulation

the relevant design formula in Code for design of steel structures (GB50017) were modified with the reference of existing foreign codes. And the design methods were proposed for buckling strength and postbuckling strength of aluminum plates under inplate bending. It was found that the results of proposed methods were in high accuracy and safer condition

and suitable for the stability design of aluminum plates under inplate bending.
