摘　　要：发生弯曲变形的梁横截面上内力的分析是研究其承载能力的基础,通过对各教材中剪力图和弯矩图绘制方法的对比分析,得出只需确定控制点内力值就可绘制内力图的控制点法,并使用计算准则结合剪力图面积计算控制点内力值,该方法不仅快速,而且准确率高。The bearing capacity of a beam that has undergone bending deformation lies in the internal forces on the cross section of the beam.By comparing and analyzing the drawing methods of shear diagram and bending moment diagram in various textbooks,the control point method can be used to draw internal force diagram only by determining the internal force value of the control point,and the internal force value of the control point can be calculated by combining the calculation criteria with the area of the shear diagram.It’s found that this method is fast with high accuracy.

关 键 词：内力图 控制点法 计算准则 积分关系
