In this study, the cracking and maximum torsional moment values of reinforced concrete walls obtained from the experiments were compared with those obtained from finite element analyses and various standards. Reinforced concrete walls were designed according to the Turkey Building Earthquake Code 2018 (TBEC 2018) and the Turkish Standard 500 (TS500 2000). The purpose of this study is to compare the cracking and maximum torsional moments of reinforced concrete walls obtained using different methods. Data from the reinforced concrete wall tests were used for comparison. After the experimental tests, the ANSYS finite element program was used to perform numerical analyses. Finally, TS500 2000, ACI 318–14, and Eurocode 2 were used to obtain the theoretical values of the cracking and maximum torsional moment. All the data obtained from the three methods were compared and evaluated using tables and graphics. When the results are compared considering the length/width ratios (aspect ratios) of the walls, the calculation results show that the larger cross-section reinforced concrete walls have higher cracking and maximum torsional moments. It was determined that there was a 50% increase in the average cracking torsional moment with an increase in the aspect ratio from 5 to 7. This increase was calculated as 33% at the maximum torsional moment. When the results are compared according to different methods, it was observed that the cracking torsional moment values obtained from ANSYS analyses were similar to those obtained from the standards. The experimental cracking torsional moments were higher than those obtained using the other two methods. The maximum torsional moments obtained from the three methods were similar. The analysis results show that the standard-based calculations offer more conservative results.
