Abstract:
Based on statistical analysis, this paper discusses a theoretical model for determining shear strength in steel fiber reinforced concrete beams with transverse reinforcement, using the univariate nonlinear regression of a database consisting of 100 SFRC beams with stirrups, which were analyzed and tested experimentally to shear failure. The proposed model was applied to another database with 150 SFRC beams with transverse reinforcement, which had also experienced shear failure. To check whether the model works for ultimate shear stresses, the effectiveness of the proposed equation was measured by statistically comparing the accuracy of the shear stress values obtained through the model with those acquired through the standard equations and with the experimental values for stress present in the database. These comparisons between the theoretical and experimental results demonstrate that the developed expression efficiently predicts the shear strength of SFRC beams.
