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 standard did not mention anything about toughness or energy just the formula to calculate shear strengths.

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.
