ABSTRACT

 

This paper presents an analytical Moment-Curvature behaviour of statically determinate Glass Fiber Reinforced Self Compacting Recycled Aggregate Concrete (GFRSCRAC) beams, taking into consideration, the confinement offered by lateral ties to concrete in compression zone. A confinement model was developed based on the axial compressive strength studies on Tie Confined GFRSCRAC prisms. The confinement model thus developed from the investigation was used as a stress block for confined GFRSCRAC to generate the complete analytical Moment-Curvature behaviour. The Moment-Curvature behaviour obtained using the selected confinement model was compared with experimental results. It was observed that there was a considerable change in the values of moment curvature due to the addition of glass fiber. The benefit was more clearly in case of recycled aggregate based SCC beams. The result obtained from the predicted model is close to the experimental values.
