《地下铁道》课程中钢筋混凝土受弯构件正截面承载力计算的教学设计和实践

Pedagogical Planning on Calculating the Load-Bearing Capacity of Normal Cross-Section of Reinforced Concrete Flexual Members and Its Practice in the Course Entitled Metro

摘要: 本文根据面向本科学生而开设的《地下铁道》课程中钢筋混凝土受弯构件正截面承载力和配筋设计的教学内容，提出了便于学生理解和掌握的钢筋混凝土受弯构件正截面承载力计算方法的教学法设计，分别从单筋矩形截面梁、双筋矩形截面梁和T形截面单筋梁的承载模型提出了计算和设计受弯构件受力钢筋的推演方法和工程案例。通过对所提出教学设计的实践，不仅有利于引导学生开展创新思维，而且还能够实现预期的教学目标。

Abstract: Based on the instructional contents of the course entitled Metro concerning the load-bearing capacity of normal cross-section of reinforced concrete flexual members and their reinforcement design delivered to undergraduates, a pedagogical planning for calculating the strength of normal cross-section of flexual members is prepsented to be easily comprehended and mastered by undergraduates in this paper. Both the deductive method and engineering cases on calcluating and designing the reinforcement for flexual concrete members are also proposed from the load bearing models of beam with rectangular normal cross-section having single and double reinforcements, as well as the cross-section of T-shaped beam having single reinforcement. The practice of the pedagogical planning presented in the paper can not only help guide the undergraduates to develop innovative thinking, but also help achieve expected teaching aims as planned.
