Dear Friends
How can I do multimodal response spectrum method of analysis with Opensees?

How can I call variables from a text file in my input file ?

How can I model post buckling behavior with Steel02 material?
Do you have any example of braces modeled with this material?
Tnx

Dear Friends,
Can we use Reinforcing Steel Material in modeling buckling for braces? What changes should be done on specific parameters?

Yes.

when does these messages appear? What is fault ?
1- Large trial compressive strain
2- Warning – ForceBeamColumn2d: :update – failed to get compatible element forces & deformations for element: 67
3- SectionAggregator: : getSectionFlexibility - - singular section stiffness

what is the way to release a degree of freedom in an element?
For example releasing M3 in both sides of a beam element.
Thanks
