How to calculate strength degradation in a hysteresis loop (cyclic loading)?

I understand that the peak load at that specific deformation is to be taken but how do we get the % in degradation (is it by % decrease from one load to another)? Additionally, do we compare peak...

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.

Is the area under the load-deflection curve of concrete tested under direct shear considered as "shear toughness"?

I tested 100x100x500mm concrete prisms under direct shear using the JSCE-SF 6 standards. Is calculating the area under the load-deflection curve considered as shear toughness or shear energy? The...

Is it realistic to have a concrete material with 35 MPa compressive strength (28-days) but with only a 6900Mpa Elastic Modulus?

I conducted a compressive uniaxial stress-strain test for normal concrete, it achieved a peak stress of 35 MPa but when i calculated the young's modulus from the stress-strain curve in excel, it...

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...
