Title: Assigning different section geometry
Post by: Faezeh on November 17, 2013, 12:16:15 AM

Hi,

I am analysing a column-beam joint structure. I am using fiber-based beam elements. I have modelled this with 3 elements. My aim is to assign each of the beam and column with different beam sections of varied geometry and material props. If anyone could help me with the command that I can do this it would be greatly appreciated.

Thanks,

Have you written your own element for the fiber model?  If yes, then:

1. You can use the material parameters d(*) to define the section properties you want to have.

2. If the material model is non-linear, inelastic you need to add history variables to retain the material parameters necessary to define the model behavior.

3. Each element will probably have its own material model or alternatively you can define new arrays to store the iindividual parameters for each element.

The elements in feappv/feap are not compatible with a fiber model formulation.

Yes The element is a user written element.
Thank you for your response and help.
