快速面积矩法绘制结构变形图

Drawing structural deformation diagram by fast moment-area method

目前有面积矩法可以求解静定结构的变形和位移,本文提出的快速面积矩法不仅可以定量求解结构关键点的位移和转角,并且可以定量和定性地绘制结构变形图,该方法几何关系直观、概念清晰,降低了快速绘制结构变形图的难度。

The area moment method can solve the deformation and displacement of statically determinate structure. The fast moment area method presented in this paper can not only solve the displacement and angle of the structural key points quantitatively, but can also quantitatively and qualitatively draw structural deformation diagram. This method has intuitive geometrical relationship and clear concept, and can reduce the difficulty of drawing the structure deformation diagram rapidly.
