Composite Columns in Cross Section Editor

SOFiSTiK SOFiPLUS
1

Hello,

First of all please feel free to respond in German or English. Whichever you prefer.

I am trying to model a composite column in the cross section editor but am having trouble doing so. The cross section should look as illustrated in the image. It will be a steel rectangular tube filled with concrete. The 4 circle represent tendons which will pre-stress the column. Could you please advise how this cross section should be created? I am having trouble with if it should be a new solid section out of steel, then an opening, then filled with concrete, or in what order it should be created.

Thank you for your help,

Erik

Hello Erik,

you can define such a cross section fast:

  • Use in SOFiPLUS → New Solid Section → Composite or Steel
  • Master material should be the structural steel in the first dialog ‘Section Properties’
  • Define with the command ‘Rolled Steel Shapes’ a SH standard steel profile with:
    ‘Material for Filling of hollow sections’ → input of the concrete material
    In the case of a different geometry of the steel SH profile, you can modify single geometriy values in this dialog
  • At least define the reinforcement with the dialog ‘Single Reinforcement’
    Here one layer should be available in the dialog ‘Cross Section Properties ‘tab ‘Reinforcement Layers’

Calculate the cross section → ready.
