摘要
应用由载荷、剪力和弯矩间的微分关系,通过逆运算而得到一种新的内力图作图方法——"面积法"。可通过计算相应图形面积的方法来作复杂荷载情况下的内力图,不必求解剪力方程和弯矩方程。
By studying the relationships of load,shearing force and bend moment,by athwart calculation,a new drawing method to draw internal force drawings,namely,'method of proportion',was achieved.An internal force drawing with complicated load can he drawn by calculating the proportion of the related graphs.There is no need to figure it out with shearing force formula and bend moment formula.
