Gap in hysteretic material

[gswarup]

HI !

Can anyone suggest me, how can I provide an initial gap in hysteretic material in OpenSees?

I'll highly appreciate any suggestion regarding that.

Thanks and Regards,

You may refer to the following gap materials:

Hi ismailqeshta!... thanks a lot for the response. I've gone through those examples already but still was stuck at the problem.

Meanwhile, I've found a solution. I've used one ElasticPPGap material and one Hysteretic material in series. After the gap, the combined stiffness of the two materials should be such that it represents the force deformation behaviour I want to specify for the material. It's now running fine.

Thanks a lot,
