RambergOsgoodSteel Material

[ssami]

Hi everyone,

I modeled a SDOF system with the RambergOsgoodSteel material, but when I want to conduct a nonlinear time history analysis under an earthquake, the following message appears:

WARNING could not create uniaxialMaterial RambergOsgoodSteel

I would be really grateful, if anyone could help me in this regard.

Please provide more details. If the material can be created for an SDOF system, it can be created for a nonlinear time history analysis. There must be an error in your input.
