摘　　要：介绍了受弯构件正截面相对受压区高度的基本概念及承载力设计的基本假定,结合中欧混凝土规范的混凝土及钢筋材料相关参数推导了受弯构件相对界限受压区高度的计算公式,分析了中欧混凝土规范中相对界限受压区高度的取值及含义,得出了中欧规范在设计中受压区高度的取值范围的差异,为设计人员更好的学习国内外规范提供参考。The basic concept of relatively height of ultimate compressive region of the normal section of the bending member and the basic assumptions for the design of the bearing capacity are introduced,and the calculation formula of relatively height of ultimate compressive region of the bending member is derived by combining the concrete and rebar of the China code and Eurocode.The value and meaning of relatively height of ultimate compressive region in China code and Eurocode is analyzed,In addition,the differences of value range of the compressive region height in the design of the China code and Eurocode is obtained,which provides a reference for designers to better learn the domestic and foreign codes.
