【摘要】 大偏心受压构件正截面承载力计算是混凝土结构课程的重要教学内容。当学生进行大偏心受压构件正截面承载力计算时,可能会遇到受压钢筋达不到屈服强度的情况。此时如何进行结构计算是学生学习这部分内容的一个难题。通过算例分析,对比了受压钢筋达不到屈服强度时的两种计算方法。在此基础上,对如何讲授这部分教学内容进行了讨论。更多还原

【Abstract】 The calculation of the bearing capacity of the normal section of a large eccentric compression member is an important teaching content of the concrete structure course. When students design the cross section of the large eccentric compression member,the situation that the compressive reinforcement does not yield could occur. How to design the structure in this situation is a difficult problem for students. In this paper,two methods of how to carry out the section design when the compressive reinforcement does not yield are compared. Based on the analyses,this paper has discussed how to teach this part of content.更多还原
