zero stresses

[Jfoyian]

I noticed that I'm getting zero stress values after the first 2 time steps till the end of my pushover analysis. I use the following command to get the output:

recorder Element -file Data/material.out -time -ele 1 section 1 fiber 80 4 1 stressStrain;

at the coordinates (80,4) I have unconfined concrete with material tag 1.
I'm using concrete02.
What could be the problem?

what is the strain?
you may be in tension, past the max strain...
