Time History Analysis

[akshaysomkuwar123]

Thank you very much for the help. I will try to work out with the code you have provided.

This forum has been one stop solution for my OpenSees problem. I am very thankful for your kind suggestions.

I would like to know is there any way to find damping force in a member. I know OpenSees provide damping force at nodes but if one would like to extract damping force in an element is there a way to do that?

Thank you very much

some elements support the "RayleighForces" output.
However not all of them, and also they do not clearly explain what the components are.

Can we do Linear Time History Analysis using ForceBeamColumn Elements with Concrete02 and Steel02 uniaxial materials.?

What differ Linear and Non-linear Time History analysis in OpenSees STKO ?

Is Elastic section and fibre section makes the difference ???

No this would be a Nonlinear Analysis

What differ Linear and Non-linear Time History analysis in OpenSees STKO ?

Look into the published literature, it does not depend on the program.

Is Elastic section and fibre section makes the difference ???
Elastic section is elastic, fiber section is subdivided in fibers

Didn't found anything in the literature. In other software like ETAB and SAP2000, direct option is there to select Linear or Non-linear analysis. But in STKO, I don't find this option. Actually I need to compare the results of the Linear and Non-Linear Time history analysis. So I need to do both.

So any way that I can do both Linear and Non-linear on a structure?

Linear analysis:
Use elastic materials
Use Linear algorithm

Nonlinear analysis:
Use any kind of material
Use Newton (or other) algorithms

Ok thanks you so much.

Ok thanks you so much.

Could you please tell me how your dome-shaped TCL model was constructed? Did you import OpenSees through other software?
