摘　　要：针对ACI 318M-14《混凝土结构设计规范》和EM 1110-2-2104《水工钢筋混凝土结构强度设计规范》中压弯构件正截面承载力计算问题,根据规范的原则假定,提出截面在单侧配筋或双侧配筋条件下按受拉/受压控制的计算方法,编制相应计算程序并进行实例计算。结果表明:该计算方法可应用于压弯/纯弯构件正截面承载力计算,提高工作效率。In view of the calculation of the bearing capacity on normal section of compression-flexure members in ACI 318M-14 and EM 1110-2-2104,according to the principle of assumption in the code,the calculation method for bearing capacity on the section which is tension or stress controlled under the condition of single-sided reinforcement or double-sided reinforcement is proposed and corresponding calculation program is compiled to carry out the example calculation.The results show that the calculation method can effectively calculate the bearing capacity on normal section of the compression-flexure/pure bending members and improve efficiency.
