Through the analysis of the static equilibrium relationship and static moment equilibrium relationship in reinforced concrete members that are subject to tension condition, the instructional planning on the method of designing reinforcing steel bars in small and large eccentrically tensile reinforced concrete members is also presented. In particular, load decomposition method is employed to analyze the reinforcement of large eccentrically tensile reinforced concrete members. The practice of using the instructional planning presented in this paper for teaching the undergraduates the course entitled Metro and Light Rail Transit shows that the instructional planning does not only help improve the teaching quality of the course, but enhance the undergraduates’ ability and their innovative way of thinking to design the reinforcement of reinforced concrete tensile members related to subway and Light rail transit structures as well.展开更多
