Ductility of beam

[DDRJ]

Good day!

I'm new to prestressed design and just about to start reading some materials about it.
I started by reveiwing the theories of Reinfored Concrete Beam (RCB) and came accross this question: "Is there a way to quantify the ductility of RCB?"
I understand that increasing As (Area of steel) will make the section less ductile but what is/are the limit/s or figures that can be used to compare the ductility of different sections.

Thanks!

I understand that Rho as prescribed by the code gives limit to As to ensure that the section will fail in a ductile manner.
Does it mean that a section adopting rho max is more ductile than the one using rho min? but ofcourse

The section with rho min is more ductile, but you are in the wrong forum here.

Thanks AELLC for the reply.

First, Yes it is the otherway around for the ductility of beam using rho.
Second, I didnt notice that this thread was under Engineering Spreadsheets.

So I stant corrected twice'

Thanks man'
Cheers!
