Part 4: Detailed Design 4 – 41 Figure 5.12 Simplified procedure for verification of column subject to axial load and nominal moments Use of design aids Design software is becoming increasingly available. Because of the wide range of parameters involved, it is not feasible to use tabulated data for the final design. However, tabulated design data can be used to determine the denominators in Equations 5.1 and 5.2.
