Capacity optimization of reinforced concrete circular column

Abstract

The paper is all about pragmatic method of increasing structural performance of reinforced concrete circular column at the same quantity provision of the main bars. Main attention was given to the ring component of the column reinforcement. Materials were collected and treated as it may be demanded in normal design and construction processes. Circular column reinforcement fabrications were carried out as specimens with circular and spiral rings. Different angles of inclination were considered for the spiral rings at equivalent spacing of that of circular, using the same cross sectional size of steel and area of the composite element. Laboratory crushing test was carried out at the required same ages of casting and curing to obtain results. The analysed crushing strength results thus revealed considerable increase in load carrying capacity of the spirally ringed reinforced column above the circular rings at same cost implication.
