Problem Description:

How can I get the section dimensions of any tapered “I section” i.e. (web depth at the start, web depth at the end, width of the flange at start, width of the flange at the end …. etc) using OpenSTAAD function?

Solution:

You may use function GetSectionPropertyValuesEx

Parameter:

• [input] propNo: Section Property ID
• [input] propType: Number referring to Section Type Code table
• [input] propValues: section property parameters (get array size by calling the API GetCountofSectionPropertyValuesEx)

A sample VBA syntax:

 Dim nSectionPropValuesCount As Long

 Dim RetVal As Long

 Dim propValues() As Double

 Dim propType As Long

 Dim refID As Long

 

 Set objOpenStaad = GetObject(, "StaadPro.OpenSTAAD")

 nSectionPropValuesCount = objOpenStaad.Property.GetCountofSectionPropertyValuesEx() '24 maxValue of theProperty Array.

 ReDim propValues(nSectionPropValuesCount)

 refID = 6

 RetVal = objOpenStaad.Property.GetSectionPropertyValuesEx(refID, propType, propValues)

'0-6 index will have value F1-F7 respectively

Output:
