摘　　要：探讨了平截面假定的概念实质,分析了平截面假定在材料力学、钢筋混凝土结构和预应力混凝土结构中的几种常见应用情况,利用钢筋混凝土梁三分点加载实验验证了平截面假定的适用性.This paper studies the substance of plane section assumption,and analyzes several common cases in the field of civil engineering,such as the field of mechanics of material,reinforced concrete structure and prestressed reinforced concrete structure.The applicability of plane section assumption is verified using the method of three-point loading in the test of reinforced concrete beam.

关 键 词：平截面假定 应变 钢筋混凝土 预应力混凝土
