摘　　要：基于欧洲标准进行项目设计是中国企业"走出去"的关键。本文详细阐述了欧洲混凝土标准(EN 1992-1-1(2004))的设计原则、基本理论,在此基础上结合欧洲混凝土标准在材料及正截面计算等方面的设计假定和特点,分析截面的应力-应变关系,提出了一种采用弯矩-轴力"包络图"进行钢筋混凝土正截面承载力设计的方法。实际算例证明,该设计方法具备高效性、可行性和可靠性。Designing based on Eurocode is a key for Chinese companies to"go global".In this article,the design principles and basic theories of the EN concrete standards(EN 1992—1—1(2004))are elaborated.Combining the design assumptions and characteristics of the European Concrete Standard in terms of materials and calculation of the normal section,the stress-strain relationship of the section is analyzed,and the design method of normal section bearing capacity of reinforced concrete is proposed using the"envelope diagram"of moment-axial force.The actual calculation example proves that the design method is efficient,feasible and reliable.
