Dear Seismostruct,
I am working with Park hysteretic multilinear model. I have to model an asymmetric spring behavior but SeismoStruct implements the Park model only adopting the same stiffness in tension and compression.

It would be possible to modify the software subroutine in order to define two different stiffnesses in tension and compression? I think that is a significant improvement quite easy to do. I would need this modify, if possible, really urgently. Please let me know.

Looking forward to hearing from you.

Sincerely.

Unfortunately, although the change of the model itself is fairly easy to handle, the fact that the currect development release is not stable enough to be distributed, as well as issues like backwards compatibility, make it difficult to apply such change soon.

However, we will consider the change is a subsequent release.
