钢筋混凝土偏心受压构件正截面受力钢筋计算的教学设计与实践
Instructional Planning and Practice for Calculating Reinforcing Steel Bars in the Normal Cross-Section of Reinforced Concrete Members Subject to Eccentric Compression

钢筋混凝土偏心受压构件正截面受力钢筋的设计是为本科学生开设的《地下铁道与轻轨》课程中的重要教学内容之一。由于这部分教学内容涉及较多的基本概念和理论推导，学生对设计方法的理解和掌握尚存在较大的困难。本文结合课程的教学内容，就钢筋混凝土偏心受压构件中受力钢筋的计算方法进行理论推导，并基于偏心受压构件的静力和静力矩平衡提出了混凝土偏心受压构件中受力钢筋配置方法的教学设计。通过在《地下铁道与轻轨》课程中的教学实践表明，本文所研究和提出的教学设计有利于学生理解和掌握钢筋混凝土偏心受压构件中受力钢筋的计算和设计方法，并能启发和引导学生树立创新思维的意识。
The design of reinforcing steel bars in the normal cross-section of reinforced concrete members subject to eccentric compression is one of the key instructional contents in the course entitled “Metro and Light Rail Transit” offered to undergraduates. As the instructional content involves many basic concepts and theoretical derivation, undergraduates still have great difficulties in understanding and mastering the design method. In this paper, combined with the teaching contents of the course, the method for calculating the reinforcing steel bars in reinforced concrete members due to eccentric compressive load is theoretically deduced, and based on both the static equilibrium and static moment equilibrium of eccentric compressive members, the teaching contents of designing the reinforcing steel bars in the normal cross-section of reinforced concrete members subject to eccentric compression are also presented. The teaching practice in the course entitled “Metro and Light Rail Transit” shows that the instructional planning studied and presented in this paper is conducive to helping undergraduates comprehend and master the calculation and design method of reinforcement in reinforced concrete members subject to eccentric compression and can inspire and guide undergraduates to establish the awareness of innovative thinking.
