Abstract

An improved analytical model to predict the ultimate shear capacity of a self-consolidating concrete (SCC) flexural member is presented. SCC behaves differently to normal concrete because of its unique composition and mix proportions, which alter the shear resisting mechanisms in the member. SCC has found a wide range of applications due to its excellent deformability and high resistance to segregation and bleeding, but the lack of an adequate model that could help analysts predict the shear capacity of SCC beams is one of the main barriers to its acceptance in routine design practice. The model presented in this paper was developed considering all the factors that influence the shear capacity of SCC beams. The test results of an experimental study conducted to validate the accuracy of the proposed model are also provided in this paper; the model's efficacy was also checked using test results reported by other researchers. The results predicted by the model showed good agreement with the experimental test data.
