摘要：
To improve the calculation accuracy of the bearing capacity of stainless steel reinforced concrete flexural members, based on the continuous strength method, a stainless steel constitutive model that allowed for strain hardening was added into calculation. An iterative calculation method of normal section bearing capacity under different bearing capacity limit states was proposed based on the plane section assumption. Considering the complexity of iterative algorithm for component design, the stainless steel reinforcements adopt a bilinear constitutive model that allowed for strain hardening. It was assumed that the stainless steel reinforced concrete flexural members were usually damaged due to the crushing of concrete. The test results are compared with the calculation results of the standard, iterative and simplified methods based on 15 sets of experimental data. The results show that the iterative and simplified methods provide more accurate results than the specifications. To verify the correlation between the iterative method and the simplified method, an additional 35 groups of examples were added to the 15 sets of experimental data, and the two methods were used for calculation. The correlation coefficient between the two calculation results is 0.994, which shows that the calculation results of the two methods agree well. © 2022, The Editorial Board of Journal of Basic Science and Engineering.
