板件宽厚比对交叉钢梁稳定性影响研究

open access: yesJianzhu Gangjiegou Jinzhan, 2021
对中、美、欧现行规范关于钢结构截面类型及宽厚比限值的要求进行了归纳比较,利用ABAQUS有限元软件进行了单根H形钢梁考虑初始缺陷的屈曲承载力分析并与规范公式计算结果进行了对比。在此基础之上,以雄安站站房雨棚钢结构为背景,选取具有代表性的区域建立空间交叉H形钢梁精细有限元模型。对不同板件宽厚比的空间交叉H形钢梁进行了非线性屈曲承载力分析,研究了翼缘宽厚比及腹板高厚比对空间交叉H形钢梁局部稳定性和屈曲性能的影响。研究结果表明:ABAQUS模型对钢梁整体稳定性计算结果与规范公式吻合度较高 ...
