https://orcid.org/0000-0002-8202-1731
Based on the constitutive relation of recycled aggregate concrete (RAC, referred to as recycled concrete), from the calculation formulas of the equivalent rectangular block parameters in the compression zone of recycled concrete beams under different recycled coarse aggregate replacement ratios, the calculation formulas of the key parameters 훼1 and 훽1 of recycled concrete are deduced. Based on 훼1 and 훽1, the flexural bearing capacity of recycled concrete beams is given. In addition, the nonlinear finite element method is applied, and the simulation results are compared with the calculation results to verify the accuracy of the calculation results. Then, the limit compression zone height and maximum reinforcement ratio of recycled concrete beams, as well as the variation characters of compression zone height and reinforcement ratio under certain size and load are analyzed and obtained.
