Abstract:

A simple procedure for calculating effective torsional rigidity of reinforced concrete (RC) members is presented. The proposed method relates 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. Prior to cracking, the elastic and uncracked torsional rigidity of the section is used, while after the formation of torsional cracking, the proposed procedure interpolates between torsional rigidities immediately after cracking, and that at the ultimate limit state. The procedure is verified by comparing predictions with test data available in the literature. Comparison between the computed and experimental torque-twist curves shows that the proposed procedure for computing effective torsional rigidity is reasonably accurate.
