Serviceability limit state (Columns: BS 5950)
The column is assessed for sway and the following values are reported for each stack:
- Sway X (mm) and λcritx
- Sway Y (mm) and λcrity
- Sway X-Y (mm)
Depending on the reported λcrit the column is classified as Sway or Non sway accordingly.
Note: A sway assessment is only performed for the column if the Lambda 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
Lambda Crit Check box for those columns for which a sway assessment would be
inappropriate
