Fiber section confined concrete

[kyungtae79]

Hello everyone,

Is there anyone who is familiar with creating a fiber section for an octagonal concrete cross section?

I would like to use a factor to account for confined concrete (core) in defining the core concrete.

The factor will be used to increase the concrete strength.

I am looking for any reference showing the factor or how to define the increase to make the fiber section.

I will appreciate any help on this.


All the best,
Kyungtae Kim

To get an idea on how to create octagonal confined RC section I suggest you to look at the example file for the rectangular RC section (http://opensees.berkeley.edu/wiki/index ... on_Example).
