冷弯薄壁复杂卷边槽钢受弯构件稳定性能分析

摘要

The stability behavior of cold-formed thin-walled steel flexural channels with complex edge stiffeners including three types of stiffeners was analyzed by nonlinear finite element analysis using software ANSYS. The results showed that the stiffener is a key factor that affects the buck-ling mode and bending strength. And the bending strength under non-pure bending is higher than that under pure bending.%采用有限元软件ANSYS对3种加劲形式冷弯薄壁复杂卷边槽钢受弯构件的稳定性能进行了非线性分析，结果表明：加劲形式是影响构件屈曲模式和抗弯承载力的重要因素，构件在非纯弯状态下的抗弯承载力均大于纯弯状态下的抗弯承载力。
