Topic: Cyclic Loading Atena
My name is Ingrid.
I'm doing one fram with two bays model with one cycle load (Bidimensional 2D). But i have few questions about it.
1) How can i defined the parameter tension stiffening (concrete), i read in any papers that the deffault (Model code) is 0,4. But, there are any equation for modified or how can i define this value?
2) How could define the value unloading factor (concrete)?. I didn't find many information for unsderstand this value...
3) My model have one cyclic load. So, i modelled the stirrups and longitudinal steel like CCCyclingReinforcement, but i woulk like know how can i determine the values R, c1 and c2 from Menengotto-Pinto...?
