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.

You can use standard ASTM E8 (Standard Test Methods for Tension Testing of Metallic Materials) for preparing tensile test specimen.

Zi Sheng Tang

You can refer BS EN ISO 527-1:1996.

I was using it for the tensile strength of adhesives. Can email me for further information at [email protected].

Good question

Ahmed Mahdi

Interesting.
