钢结构压弯构件整体稳定问题的教学探讨

Research on the overall stability problem teaching for compression-bending steel member

从失稳现象、力学模型、失稳准则、公式构建几个方面,对比压弯钢构件整体失稳两种形式的解决方法,引导学生理解和掌握压弯构件整体稳定的概念和问题的求解途径,并从稳定计算公式的演绎过程中,深刻体会力学理论在钢构件设计中应用的重要性,掌握应用力学知识分析结构工程问题的思维方法。

By comparing the two forms of solution about overall stability problems of compression-bending steel member, this paper guides students to understand and grasp the concepts and solution methods of overall stability from instability phenomenon, mechanical model, instability criterion and formula construction. And through the deduction procedure of stability formula, students are led to understand the importance of mechanics theory in the design of steel structures, and get the thinking method of applying mechanics knowledge to analyze structural engineering problems.
