摘要:
拱形波纹钢屋盖结构由冷成型弧形槽型板组截面构件锁边咬合而成,其极限承载能力受多种因素的影响,并主要取决于其稳定承载性能 .文中根据拱形波纹钢屋盖结构的成型特性和工作机理,在所建立的实体有限元计算模型中,采用能够反映结构特殊工作状态的边界约束条件,对结构在半跨和全跨竖向荷载作用下的屈曲模态以及其稳定承载能力等屈曲性能进行理论分析 .理论计算结果表明,拱形波纹钢屋盖结构的屈曲性能不仅与结构几何尺寸有关,而且取决于截面的形状和荷载作用形式 .计算结果与试验结果和按《拱型波纹钢屋盖结构技术规程 (报批稿 )》简化方法计算结果,分别进行比较分析
Abstract:
An arch corrugated steel roof (ACSR) is constructed by lockstitching the borders of cold-formed thin-walled curved rectangle or trapezium channel sections shaped by sheet steel panel. The ultimate bearing capacity of this structure is affected by varied factors and depends primarily on its stability bearing capacity. Based on forming characteristics and operating mechanism of this structure and adopting boundary constraint conditions reflecting special operating mode of the structure, the authors establish a solid finite element model and carry out a theoretical analysis on the buckling modes and stability bearing behavior of the structure subjecting to half-span or full-span vertical uniform loading. The theoretical results show that the buckling behavior of this structure not only relates to geometrical sizes of the structure, but also depends on the shape of section and the type of loading. The results are also compared respectively with the full-sized model test results and those according to simplified method of “Technical Specification for ACSR”(edition for authorizing), it is illustrated that the method used in this paper is more useful and accurate.
