Re: Stress Resultant Plasticity Model

Thanks Prof., I went through the post, it is about a bidirectional section. I want to know what model is used to determine stress resultant yield surface for a normal (unidirectional) fiber section in opensees. Can you please provide some information about that.

Thanks

Re: element zeroLengthSection-The moment curvature analysis cannot output the stress and strain of the fiber

The output you are getting is not bending moment but it is the pseudotime. There must be something wrong with your code due to which it is unable to record the stress and strain and you are only getting pseudotime as an output. Thank you for your reply. Could you please help me to see how to modify...

Joint2D

Dear All,
I had a question about Joint2D in OpenSEES.
Is the joint2D valid for modelling panel zone in steel frames also or is it meant to be used for modelling panel zone in RC frames only?

Thanks

Re: large displacement large strain

An easy way to do both material and geometric nonlinear with frame elements is to use a "corotational mesh": https://wp.me/pbejzW-Bh Sir, I read your post. I just wanted to ask that when you say co-rotational mesh, do you mean using multiple non-linear frame elements(force/displacement based) with ...

Re: large displacement large strain

Thanks Ashok for your reply. I have not thought of including geometric non-linearity into my material model. Can you suggest of some simple examples to begin with or refer to a some problem in which the effects of geometric non-linearity has been taken into account in the material model itself. than...

large displacement large strain

Dear all,
Is it possible to perform a large displacement large strain non-linear analysis in OpenSEES? The co-rotational transformation as mentioned in the documentation is based on large displacement-small strain formulation.

Thanks
