摘　　要：根据近年来国内外高强混凝土的研究成果，总结了高强混凝土强度指标的换算关系，提出正截面承载力计算用的高强混凝土受压应力－应变曲线。根据该关系曲线分析了高强混凝土构件的正截面承载力，建议了应力－应变曲线参数的取值。在此基础上，进一步给出了等效矩形应力图形系数。The concrete strength - in the new modification version of Chines concrete design cede is expanded from C60 to C80. This paper is the background for the modification version of the design code. The conversion factors between concrete strengths for high-strength concrete (HSC) is suggested. Then, a simple form of the stress-strain curve is proposed to calculate the capacity of normal section for high-strength concrete. The parameters of the suggested curve are analyzed by comparing theoretical results with that of the test. The equivalent rectangular stress block coefficients are also given by the suggested curve.
