摘　　要：以单筋矩形截面受弯承载力计算为题,根据规范就构件正截面承载力计算所遵循的计算假定条件,计算出构件正截面受弯承载力的理论解,并以此为根据,通过分析规范正文中的正截面承载力计算公式和规范附录F的计算公式对单筋矩形截面受弯承载力计算的配筋结果,阐明用规范附录F计算方法计算的配筋结果的安全性。According to the hypotheses adopted in the calculation of flexural bearing capacity of reinforced concrete elements proposed in the （ Code for design of concrete structures） the theory solution is presented for the singly reinforced rectangular sections, then through comparison among calculation results obtained from theory solution, two groups of calculation formulas listed in chapter 7 and appendix F respectively in the（Code for design of concrete structures）the rationality of calculation results obtained from appendix F formulas is validated.
