Serviceability limit state (Columns: EC3 Eurocode)
The column is assessed for sway and the following values are reported for each stack:
-
Sway X and αcritx
-
Sway Y and αcrity
-
Sway X-Y
Depending on the reported αcrit the column is classified as Sway or Non sway accordingly.
Note: A sway assessment is only performed for the column if the Alpha Crit Check box
is checked on the Column Properties dialog. If very short columns exist in the
building model these can distort the overall sway classification for the
building. For this reason you may apply engineering judgement to uncheck the
Alpha Crit Check box for those columns for which a sway assessment would be
inappropriate.
