The concrete structural design principle is one of the most important courses for civil engineering. It has several characteristics such as large amount of information, comprehensive, lay equal stress on theory and practice. All of the factors make it very difficult for both teaching and learning. In this paper, the characteristics of concrete structure design principle course were analyzed; then, the flow chart method was introduced on the basis of introducing the flowchart symbol and the basic structure. Then, the feasibility of using flow chart method to display the key content of concrete structural design principle was proofed. Finally, take design of torsion-shear-bending member as an example, it proofs that using flow chart method in teaching important and difficult points of concrete structure design principle can produced a better effect.
