摘　　要：文章以作用于梁上的横向分布力集度与剪力、弯矩的微分关系为基础,归纳总结了几种荷载作用下剪力图、弯矩图的特征。掌握这些特征就能不写内力方程而根据外力直接画出相应的剪力图和弯矩图。The characteristics of shear force diagram and bending moment diagram under several loads are summarized based on the differential relationship between distributed load and shear force and bending moment.By mastering these characteristics,we can draw the corresponding shear force diagram and bending moment diagram according to the external force without writing the internal force equations.

关 键 词：剪力图 弯矩图 微分关系 积分关系
