Wide Columns#

Depending on the section ratio of the physical column and the respective settings, different analytical model representation applies. The figure below shows the two mechanisms at play.

  • Mechanism 1: Wide Columns in General (blue):
    Decides whether or not a physical column is treated as a wide column based on its section ratio compared to the Wide Columns - Minimum Section Ratio parameter (1) in the settings.
  • Mechanism 2: Create Analytical Panels for Columns (green)
    Decides wether a physical column is represented by an analytical member or an anlytical panel based on the Create Analytical Panels for Columns parameter (2a) and the Create Analytical Panels for Columns - Minimum Section Ratio (2b) in the settings.

Mechanisms of treatment for wide columns#

Examples of Wide Columns:

Examples of Column Treatment based on their section ratio and settings

Examples of column treatment based on section ratio compared and settings#

  • Top left:
    Actual column section ratio smaller than Wide Columns - Minimum Section Ratio parameter (1), column is not considered a wide column. Therefore analytical members of beams and column are brought together (if possible).
  • Top right:
    Actual column section ratio larger than Wide Columns - Minimum Section Ratio parameter (1), column is considered a wide column. Therefore analytical members of beams and column are not brought together but connected with a rigid link.
  • Bottom left:
    Actual column section ratio larger than Wide Columns - Minimum Section Ratio parameter (1), column is considered a wide column. Because Create Analytical Panels for Columns - Minimum Section Ratio (2b) is set to No, the column is represented as an analytical member.
  • Bottom right:
    Actual column section ratio larger than Wide Columns - Minimum Section Ratio parameter (1), column is considered a wide column. Because Create Analytical Panels for Columns - Minimum Section Ratio (2b) is set to Yes, the column is represented as an analytical panel.

Important

Offset boundaries prevail over this setting. If the offset limits do not allow the analytical members for the beam and column to align, a rigid link is created notwithstanding this parameter.
