Data for: Optimum performance of axially compressed concrete columns with multi-spiral reinforcement
Results of Finite Element Analysis of multi-spiral reinforced columns. Contains 552 data points of all combinations of 5S4 type of reinforcement below 3% amount of steel. The diameters of the reinforcing bars corresponded to the imperial rebar scale from #3 (approx D10) to #7 (approx D22), the outer diameter of the small spiral ranged from 120~mm to 260~mm with 10~mm step, and three different values of the spiral pitch, 55~mm, 75~mm, and 95~mm were investigated. Table data contain reached peak stress and strain at peak stress in a uniaxial compression loading. The reinforcement combinations are sorted using clyster analysis to the groups based on the similarities in both, reinforcement and perfrmance.
