| Abstract: | 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. |
