1、下面总结了各种结构弯矩图的绘制及图例：一、 方法步骤1、确定支反力的大小和方向（一般情况心算即可计算出支反力）悬臂式刚架不必先求支反力；简支式刚架取整体为分离体求反力；求三铰式刚架的水平反力以中间铰C的某一边为分离体；对于主从结构的复杂式刚架，注意“先从后主”的计算顺序；对于复杂的组合结构，注意寻找求出支反力的突破口。2、对于悬臂式刚架，从自由端开始，按照分段叠加法，逐段求作M图（M图画在受拉一侧）；对于其它形式的刚架，从支座端开始，按照分段叠加法，逐段求作M图（M图画在受拉一侧）。二、 观察检验M图的正确性1、观察各个关键点和梁段的M图特点是否相符铰心的弯矩一定为零；集中力偶作用点的弯矩有突
2、变，突变值与集中力偶相等；集中力作用点的弯矩有折角；均布荷载作用段的M图是抛物线，其凹凸方向与荷载方向要符合“弓箭法则”；2、结构中的链杆（二力杆）没有弯矩；3、结构中所有结点的杆端弯矩必须符合平衡特点。button. Select login rule button above the rule number menu under .
