Abstract: Experimental work was aimed to study ductility behavior of plain concrete with spiral reinforcement, and fibrous concrete subjected to axial loading. Specimens were prepared as per IS code and tested. Based on the study, the following conclusions are drawn; a) Spiral reinforcements may be provided on a selective basis when the structure demands additional ductility requirements, b) To minimize the possibility separation of cover concrete portions from the core, diameter and spacing of spirals be suitably adjusted considering other factors, such as workability and constructability, c) For large size columns, the diameter of spiral reinforcements should preferably be on the lower side to prevent excessive crushing after yielding and local failure of spirals, d) To meet higher ductility requirements, fibrous concrete along with spiral reinforcement may be adopted.
