摘　　要：为了回避以往用截面法求复杂载荷下剪力和弯矩方程的烦琐步骤,提出了一种利用积分计算梁的剪力和弯矩方程并画剪力、弯矩图的方法,最后通过两个算例验证了该方法的可行性。In order to avoid the tedious steps of calculating the equations of shear force and bending moment under complex loads by section method, a integral method for calculating the equations of shear force and bending moment is presented and drawing the shear force and bending moment diagrams is proposed.Finally, the feasibility of the method is verified by two examples according to the external force without writing the internal force equations.

关 键 词：复杂载荷 剪力图 弯矩图 积分法
