ElasticBeamColumn doesn't have that option because... well it is elastic!, hence the distribution of internal forces can be calculated with common shear and moment diagram rules. You can of course always define more nodes and hence elements along a structural member...At that point you also have to ...

If you are using a nonlinear elements (such as http://opensees.berkeley.edu/wiki/index ... mn_Element, or others NL elements) you can ask for internal forces along the element, at integration points locations. Read the NOTES on the page I linked.

To date, with OpenSees version 2.4.5, this issue (bug) is still persistent. I had forgotten this post and, getting the same problem in a new script, I found the "answer" through this old question of mine, after more than 1.5 years! (Unfortunately I spent three hours drawing my patch quadr fibers on ...

Sorry for the very basic question.
getCrds()
Does this command give the original coordinates of a Node or the updated coordinates at current step?
Thank you,

Many thanks for your reply. It was exactly what I was looking for!

1) As said above, the fact the period can be reduced after the gravity analysis is to be expected, and indeed you have this result; in your case, anyway, the reduction is quite small (8 ms). 2) The comparison between the periods you obtain with the fiber and the elastic section is not straightfoward...

Sorry, "element" was not the right word. I mean the collapse element recorder that is descripted in the paragraph "New Command in OpenSees Interpreter" of the wiki article http://opensees.berkeley.edu/wiki/index.php/Infill_Wall_Model_With_In-Plane,_Out-of-Plane_Interaction_and_Element_Removal_During...

I am still trying to figure out where they do compute the In plane displacement and out of plane displacement of the nodes involved nTagbotn(nTagbotn), nTagmidn(nTagmidn), nTagtopn(nTagtopn), and where in the code they recall the criteria(remCriteria) from the file $filenameinf. This way I could che...

Hi, does anyone know which new unixial material are the authors refferring in this recent article (paragraph 8)? http://onlinelibrary.wiley.com/doi/10.1002/eqe.2346/abstract I am particularly interested in this part "Before yielding, the yield force is updated at each integration time step using the...

Hi, I can answer to your first question. MinMax material does NOT remove the element when the minimum or maximum strain are achieved during the analysis. Simply, after that point, the material will show zero stress and tangent stiffness. The actual element will be left in the model (e.g. you will be...

Thank you dr. McKenna! I have one more question. In the source code (I checked both removeRecorder.cpp and TclRecorderCommands.cpp) I cannot find the lines where the removal criterion is checked. FROM THE WIKI: - the removal criterion is placed in a file: "$filenameinf is the file used to input the ...

To anyone who might read my previous comment, the article has been corrected in the wiki.

I certainly don't have the solution, but I can report of having the exact same problem in a parametric analysis. The problem could possibly have worsened in the latest versions of OpenSees (when I wrote this script almost two years ago I didn't notice this problem and I was using a machine with half...

Can someone please point me to the code file in SVN repository for the Collapse recorder described here:

Many thanks in advance!

I found two slight differences between what I see in the source code and what is documented in the Wiki concerning Linear Transformation. Here is an excerpt from the Wiki (http://opensees.berkeley.edu/wiki/index.php/Linear_Transformation): The x-axis along with the vecxz Vector define the xz plane. ...
