Interaction Diagram For Circular Column. Column interaction diagrams b h material properties column dimensions reinforcement detail bar size line of bars psi in k f c fy interaction diagram data line depth in k ft reinforcement requirements as in2 as min as max in2 total as in2 f for rectangular tied columns with symmetric reinforcement pn mn fpn fmn. Compute eccentricity of loads.
Every point on the interaction diagram has a unique ratio of e p m n n φ φ. The points found in this example are a pu. Figure 3 interaction diagram for general section.

Tension lap splice in a column is customarily plotted on an interaction diagram. Determine seven control points on the interaction diagram and compare the calculated values in the reference and with exact values from the complete interaction diagram generated by spcolumn engineering software program from. Where pu is known as ultimate axial load in kn and mu stands as ultimate moment in kn m in the section. Tension lap splice in a column is customarily plotted on an interaction diagram.
