The model was built using the common finite element method in the validation of the examples; the model specimen reinforcement was HRB400 rebar, and the bottom of the slab was arranged in a single layer in both directions. The yield strength of the reinforcement and the concrete strength were...
The values given in Table 1 and the bar chart demonstrated in Figure 1 reveal that coupler geometry and temperature had a higher effect on the ultimate strain of non-spliced and spliced bars compared to the other input variables. Additionally, all the quantitative inputs (i.e., bar diameter...
