摘　　要：借鉴澳大利亚《混凝土结构设计规范》(AS 3600-2001)和美国《混凝土结构设计规范》(ACI 318-05),针对钢筋混凝土双向偏心受压矩形截面构件,根据中国《混凝土结构设计规范》(GB 50010—2010)附录E算法拟合得到符合中国混凝土结构设计的极限弯矩曲线方程,比较结果显示,提出的极限弯矩曲线方程与中国《混凝土结构设计规范》(GB 50010—2010)规定的附录E算法和Nikitin算法计算结果比较接近且偏于安全,可以作为一种简便算法供工程师设计参考使用。Referring the design methods for reinforced concrete rectangular cross-section component subjected to biaxial bending and compression in codes of AS 3600-2001 ＆ ACI 318-05, an ultimate bending moment curve equation was obtained according to the calculating method of appendix E in code GB 50010--2010. Comparing different results, it is indicated that the results of obtained ultimate bending moment curve equation are close to the ones from calculating methods of appendix E in code GB 50010--2010 and of Nikitin formula. Furthermore, the obtained results are conservative. Obtained simplified calculating method can be used as a reference analysis method for civil engineers.
