EFFECTIVE TORSIONAL RIGIDITY OF REINFORCED CONCRETE MEMBERS. PAPER BY TAVIO AND SUSANTO TENG. DISCUSSION.

This brief article comments on a study that presented a simple procedure for calculating effective torsional rigidity of reinforced concrete (RC) members. The proposed method related torsional rigidity, an important parameter for 3-D analysis of RC structures, to the applied torque taking the effect of reinforcement into account. The method is applicable throughout the entire loading history from the uncracked state to the fully cracked state and even to the ultimate limit state. Comparison between the computed and experimental torque-twist curves showed that the proposed procedure for computing effective torsional rigidity is reasonably accurate. In this commentary, Filho and Filho contend that the original experimental data and conclusions are not precise. They describe their concerns and provide a data table that compares computed cracking torque with Hsu (1968) data. The original authors respond to each of the objectives outlined in this discussion, and present their own table that compares calculated cracking torques with Hsu's test data.
