摘　　要：内力图能清楚显示构件各截面内力大小和方向,在对构件进行强度校核时,内力图是最为关键的一步。而传统截面法计算很复杂,步骤十分烦琐。基于此,采用一种内力图的简便画法,避免复杂的计算,通过观察直接画出。Internal Force plans to clearly show that members of the cross-section the size and direction of internal forces, the strength of the component check, the internal force plan is the most crucial step. The traditional cross-section method is very complicated and very cumbersome steps. Based on this, we consider a map of the internal forces simple painting and avoid complex calculations, through direct observation of paint.
