Seismosoft | Earthquake Engineering Solutions

I am trying to model a connection between two plates and believe the best model to do this would be using a non-linear link; I have data recorded for a specific type of nail which follows a stress-strain curve; however, with seismostruct I am unable to model the dip in this curve where the displacement is increasing but the strength is reducing. It seems that I am only able to model a positive relationship between stress and strain, is it posssible to model this dip for my non-linear element

Dear Cianmc345,

Currently, there are 29 response curves available within SeismoStruct that may be used in a nonlinear link element. One of them that might cover your requirements is the Gen_Hyst response curve, a generic uniaxial response curve characterised by Pinching effect and by four deterioration modes including strength deterioration, peak stress deterioration, reloading and unloading stiffness deterioration.

That's fantastic thanks for your help Zoi
