摘要
拱形波纹钢屋盖结构是一种薄壁轻型钢结构,由于其截面形式复杂,在荷载作用下的结构整体稳定与板组局部稳定是其研究重点.采用有限元法对波纹钢屋盖结构的一种截面形式-波纹槽型截面板组进行了轴心受压下的局部相关屈曲特征值分析,研究其在各种条件变化下的屈曲特性,得到的分析结论能用于指导工程实践.
Metal Corrugated Arch Roof is a typical kind of thin-walled steel structures. The investigation of its overall stability and local stability is a major domain because of its complex section. Finite Element Method is used to analyze the interactive local buckling behavior of channel corrugated plate assemblies under axial compression. The analyses focus on the influence of various corrugation forms, corrugation heights and different lateral constraining intensity of flange. The conclusions can be used to direct practice.
