Dear Seismostruct team,
For modeling of Concrete Cracked Sections, and checking of Performance of this sections during next loading (earthquakes), it would be better if for example this fibers which i show in this image can be omitted for a few fiber sections along the element.
I mean, users or software can omit effect of this triangle layers of section to indicate the depth of crack by just selecting this layers.
Please see the image:

I'd be glad to know your opinion.

Hi Salar,

Thank you for the suggestion. Note however that the effect of cracking is accounted for directly from the concrete material models, i.e. when the tensile strain exceed the maximum value the concrete stess is zero.

I know that.I mean for analysis of damaged element it would be better to indicate that in FIBER BEAM-COLUMN ELEMENT

Hi
It would be great if anyone could give me idea about how to model cracked concrete? I want to model a frame that has cracked concrete or already damaged concrete in its column.How to do that?

You could assign a very small tensile stress/strain limit to the concrete. Or, you could perform a section analysis to determine the cracked moment of inertia using elastic elements. It really does depend on the type of analysis you are going to perform and the results you wish to capture.
