Section Geometry

• Rectangular, circular, or irregular shapes
• Equally-spaced bars - rectangular or circular layout
• Rectangular layout with equal number of bars on each side
• Rectangular layout with a different number of bars on each side
• Irregular pattern
• Tied, spiral, or other (strength reduction factors may be modified)

Design Parameters

• Clear cover to bars or ties
• Bar spacing
• Minimum and maximum reinforcement ratios
• Design-to-required ratio
• Column height
• Sway or nonsway column
• Section and material properties of framing members to compute effective length factors
• Option to input effective length factors
• Cracked-section coefficients for beams and columns

Loads

• Factored loads and moments
• Service loads and moments
• Load combination factors
• Range of axial loads - moment capacities are computed
• Control points - key capacity points are computedG30.18, prEN 10080, or user-defined

Output

• Graphical printout of the column interaction diagram or contour plot, along with a scaled cross-section of the column and its reinforcement and other relevant information
• For uniaxial runs, pcaColumn displays the P-M interaction diagram of the section
• For biaxial runs, pcaColumn computes the 3D failure surface of the column section; you can display the P-M interaction diagram at any Mx-My ratio or the Mx-My contour plot at any axial load value
• Input loads are shown relative to the displayed diagram or contour
• While viewing a diagram or contour, you can get the axial load, bending moment, and corresponding eccentricity values of any point by simply moving the cursor over that point
• Superimpose diagrams or contours of different columns for comparison
• Text output file that can be viewed and printed, including: echo of input data, slenderness calculations and moment magnification factors (if any), input loads, and capacities with corresponding neutral axis locations, maximum steel strains, strength reduction factors and safety factors
