what is the principle of lateral tie and longitudinal reinforcement cofiguration in geometry of a column? please see the attach file.the basic principle of deciding the type of column shape in geometry
Technically seems unsound but for researcher and engineer it is not. minimum of 4 bars could be provided only in condition where the circular column diameter is less then equal to 200 mm having passed criteria of minimum of 0.8% reinforcement and is just sufficient to provide load bearing (support type) ability similar or more in comparison to rectangular column providing safety against buckling.
It must be well judged that there must not be any lateral movement
as per all international stds , min number of long, steel in circular column is 6nos
