Checking the Active box in the Punching Analysis tab allows you to display information about the punching analysis including stresses for each critical section for any of the enveloped force sets. The values displayed are for the selected critical section(s) with the selected force set, and are not necessarily the worst case for the column. The most critical punching case can always be displayed by selecting the Max Stress Ratio button and checking Section 1.

Punching analysis plots are only available for rule set design and the design status layers.
