Abstract

The present experimental investigation has been carried out to comparatively evaluate the transverse reinforcement requirement for bottle-shaped struts in glass fiber reinforced concrete and quantify the improved performance of bottle shaped strut for different amounts of transverse reinforcement. The influence of parameters related to transverse reinforcement on the strength and serviceability behavior of bottle-shaped struts also studied. The results of this investigation reveal that the minimum web reinforcement content specified in codes is sufficient for satisfying the serviceability requirements with respect to cracking for M25 grade concrete for fiber reinforced concrete also. As the grade of concrete increases, transverse reinforcement content can be increased for increase in load carrying capacity. Provision of transverse reinforcement with 1% of glass fibers increases the load carrying capacity by as high as 70% for M25 and 90% for M40 grade concrete. Also observed that, performance of reinforced bottle shaped struts depends not only on the amount of reinforcement but also on size and spacing of transverse steel. For the same amount of transverse steel, better to provide less dia bars with close spacing to improve ductility.
