Proposed Expressions for Torsional Capacity of RPC Beams


In this study, two theoretical models were used to propose expressions for the ultimate torsional capacity of Reactive Powder Concrete (RPC) beams, by using regression analysis on test results through the use of the trail version 9 of data Fit software of Oakdale Engineering computer programs. The first model depends on the well known codes provisions for torsional capacity with adding the effect of steel fibers to the proposed expressions. The second model is regression analysis of the results of experimental torsion tests conducted on RPC beams in this investigation and previous study . Both the cracking and ultimate torsional strengths are established by this method.The proposed expression of Tcr and Tn showed good agreement with the experimental results provided by reverences.
