采用有限元程序ANSYS，对带加劲肋的冷弯薄壁型钢C形截面受弯构件在纯弯和非纯弯两种受弯状态下的力学性能进行了有限元分析，分析结果表明：构件的卷边宽度是影响试件屈曲模式的重要因素，不同的屈曲模式在纯弯与非纯弯的条件下对极限承载力的影响不尽相同。%Using the finite element software ANSYS to analysis the cold-formed steel C-shaped cross-section flexural members’mechanical prop-erties which with stiffener in pure bending and non-pure bending. The results showed that:the width of the bead member is an important factor to affect the specimen buckling mode,different modes of buckling under the conditions of pure bending and non-pure bending effect on the ulti-mate bearing capacity are not the same.
