Abstract

In this study a shear resisting model for concrete beams reinforced with non-yielding reinforcement, such as FRP rods was developed based on a non-linear finite element analysis. In the model a shear resisting force of a beam is defined as a summation of shear resisting forces by concrete in a compression zone, by shear reinforcement and other than shear reinforcement, such as aggregate interlocking, in a shear cracking zone and by concrete in a horizontal zone which links the compression zone with the shear cracking zone. It was confirmed that the shear resisting model can predict strengths for shear compression failure with reasonable accuracy.
