SHEAR STRENGTH PREDICTION OF FRP-FRC-BEAMS WITHOUT STIRRUPS

The current work examines the state of the art regarding design models to predict the shear strength of reinforced concrete beams with FRP bars and fiber reinforced concrete (FRC). A data base of previous experimental data was collected and the predictive capabilities of shear design models were investigated. A mechanical model based on the modified compression field theory (MCFT) was adapted for use to prediction of FRP-FRC beams shear strength. The design models performed satisfactorily, but there is a lack of experimental data with FRP-FRC beams. The MCFT-adapted model performs well and could be a viable solution that consider equilibrium, compatibility and constitutive relationships.
