关于结构工程理论中两个重要概念的讨论

DISCUSSION ON TWO IMPORTANT CONCEPTS IN STRUCTURE ENGINEERING THEORY

构件内一点应力状态类型的判定及几何不变体系的组成规则是结构工程理论的两个重要概念。现有的文献对这两个概念的阐述不够准确,极易引起误解。本文对这两个概念进行了深入的分析,给出了较为明晰的阐述,供工程技术人员及相关专业的师生在工作与教学中参考。

The type judgment of the stress state of a point in structural member and the component rule of stable system are two important concepts in structure engineering theory, but the exposition of the two concepts in existing documents is not accurate. In this paper, the two concepts has been deeply analyzed, and the distinct exposition has been given, which provides reference to structure engineers and teachers of relative specialty.
