摘要
随着我国经济的发展,大规格冷弯型钢作为受压构件被越来越广泛地应用于建筑工程中。钢结构主要由整体稳定控制设计,因此钢结构的整体稳定一直是建筑安全领域的研究重点。参考国内外资料,从理论上分析了不同类别初始缺陷对冷弯型钢轴心受压构件整体稳定性的影响,同时指出目前研究中的不足和进一步研究的方向。
With the economic development of China, big sized cold-formed steel structures are increasingly widely applied in construction work. Given the fact that steel structure is mainly designed based on overall stability, the study on the overall stability of steel structures is the emphases in the fields of construction safety. Based on a lot of data both at home and abroad, the effect of different types of initial imperfection on the overall stability of axial compressed cold-formed steel members is analyzed and at the same time some unsolved problems and future direction of the study are pointed out.
