Space Purlin Design Results

Space purlin design results and inadequacies of space purlins are displayed in the Space Purlins dialog. The diagonals dialog displays the axial compressive strength ratio, slenderness control, and design ratio.

Location of the Space Purlins Dialog

After the analysis is done, you can access it by clicking the Space Purlin command under the Steel Design heading in the ribbon menu Analysis and Design tab .
