What does a negative inelastic strain mean? should it be included as CDP parameters in Abaqus?

I produced negative inelastic strain in my stress-strain concrete curves (i noticed that mostly negative value were at the elastic/early stage). Do i take the negative inelastic strains and include it in the Concrete Damage Plasticity parameters or should i just take the positive inelastic strains as input and leave out the negative values.

You need to have positive ones.

Why do some researchers draw coordinate-grid lines on concrete joint especially during beam-column connection testing?

Was it to physically identify crack orientation/inclination and differentiate it between lateral, flexural, shear cracks etc? Or is it for some other function i dont know about.
