Problem Description:

How to assign Tapered I Beam Property and Material using OpenSTAAD functions (VBA and python)?

Solution:

Please use the following functions

• CreateTaperedIProperty
• AssignBeamProperty
• AssignMaterialToMember

Parameter for function CreateTaperedIProperty:

[Input] Properties: Section Properties of Tapered I section. This is a single dimensional array with array size 6.

Parameter for function AssignBeamProperty:

[Input] beam: Single or an array of integers containing list of Member Numbers

[Input] PropNo: The number ID identifying a property

Parameter for function AssignMaterialToMember:

[Input] material: Identification title of material

[Input] beam: Single or an array of integers containing list of Member Numbers

A sample VBA syntax:

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

Dim Properties(6) As Double
Dim PropNo As Long
Dim beam(3) As Long
Dim material As String

Properties(0) = 0.4 'Depth of section at start node
Properties(1) = 0.01 'Thickness of web
Properties(2) = 0.5 'Depth of section at end node
Properties(3) = 0.3 'Width of top flange
Properties(4) = 0.008 'Thickness of top flange
Properties(5) = 0.25 'Width of bottom flange
Properties(6) = 0.007 'Thickness of bottom flange
PropNo = objOpenSTAAD.Property.CreateTaperedIProperty(Properties)

beam(0) = 1
beam(1) = 3
beam(2) = 5
beam(3) = 6

objOpenSTAAD.Property.AssignBeamProperty beam, PropNo

material = "STEEL"
objOpenSTAAD.Property.AssignMaterialToMember material, beam
