混凝土结构原理是土木工程专业重要的专业基础课，是联系力学与后续专业课程的桥梁，具有概念多、计算公式多等特点，尤其是课程核心内容正截面承载力计算公式涉及的种类较多，学生完全靠死记硬背会产生畏难情绪，为此，让学生展开空间想象，构建各类正截面承载力计算简图，再借助力学平衡知识自行推导相应的计算公式，做到举一反三，达到迅速掌握核心内容的目的。

Concrete Structures principle is a major important professional basic course of civil engineering, and is a bridge of mechanics and subsequent courses. Features of the course are more concepts and formulas. Especially, the formulas of normal section bearing capacity calculation that is the core content of this course have more types. The students are afraid of difficulties if they have no good way to learn various formulas completely by rote, thus they do not learn good the core content. So this article focuses on teaching them to fishing way to build all kinds of normal section bearing capacity calculation diagram by expanding space imagination, then the corresponding formula is derived by means of mechanical equilibrium knowledge. The students do learn by analogy and better learn the part core content.
