【摘要】 材料科学的进步使得钢材的屈服强度不断提高，冷弯薄壁型钢在建筑领域得到了更多的应有。为了取得更好的经济效益，冷弯钢材的厚度变得越来越薄。作为控制冷弯薄壁型钢承载能力的几种屈曲模式之一，畸变屈曲逐步受到重视。本文在国内外对畸变屈曲研究的成果的基础上，对冷弯薄壁C形截面槽钢在轴心受压和对称轴平面内偏心压力下的畸变屈曲进行了试验研究，并与理论分析结果进行了对比分析。更多还原

【Abstract】 The developments in the strength and the corrosion resistance of the cold-formed steel make it possible to use thinner plates to achieve more economy in building constructions. As one of several strength-governing modes, distortional buckling is receiving more attentions. Based on the existing achievements around the world on the distortional buckling, experimental studies are made to explore the distortional buckling behavior of the cold-formed c-section under axial and eccentric load. Test results are compared with those from the theoretical predictions.更多还原
