摘要
在进行弯曲内力分析及内力图绘制时,学生常常混淆、容易出现错误的是内力的正负问题。笔者在有关教材规定符号方法的基础上总结出一套通俗易懂的方法,本文在介绍截面法的基础上结合实例详细地给学生介绍此种通俗易懂的内力正负规定和计算方法。
When analyzing the ＂inner bending force and drawing the inner force, students often have confusion and make mistakes on the positive and negative values of the inner force. Based on the method of the symbols prescribed by the relevant teaching materials, I summed up a set of method easy to understand. Combining the living examples, this paper elaborated the simple regulation of the positive and negative rules of the internal force and calculation methods on the basis of method of sections.
