Hello, I essentially have a multi storey elasticBeamColumn associated with a leaning column, on which I am conducting dynamic analyses. I have a reaction recorder and an acceleration recorder at each storey node; the acceleration recorder has the input timeSeries added to it, to get total accelerati...

"Want" simply means it wants a specific format for that line of code --- so the format which you have entered your Hysteretic material in, is incorrect somehow. Look over it carefully. Maybe find an example of how it has been entered before. Make sure all your variables are in fact numbers.

I'm still hoping for some feedback on this model. I will start by making it clear that I have built this model and tested it, and I am finding that some moment is transferred into element 1, albeit a small amount. So I don't think the purpose of element 1 is being achieved exactly -- I think another...

Aahashib, as per your code: # create load pattern for lateral pushover load set Hload [expr $Beamweight/20.]; # define the lateral load as a proportion of the weight so that the pseudo time equals the lateral-load coefficient when using linear load pattern set iPushNode 2; # define nodes where later...

It's actually a TCL command -- part of the language that OpenSees relies on. It's not specific to OpenSees processes. The details are provided here: https://www.tcl.tk/man/tcl8.4/TclCmd/format.htm

Essentially it does with sprintf does in MATLAB (maybe you're familiar with that...)

Hello, I have linked an image of the OpenSees model I am working on (actually a component of it, http://i.imgur.com/AaPlEAZ.png). I could use some more experienced feedback on the technique applied to this model. I am running pushover analyses and processing the data -- however there is one addition...

Hello, Playing around in Navigator to build my model, I have discovered a couple of different menu items related to ZeroLength elements. I chose the path of simply defining two nodes at the same location, placing an (undefined) element between those two nodes, Defining a ZeroLength element, and Assi...

Thanks Frank -- I managed to get OpenSees to recognize the MVLEM element, but for the past couple weeks, my issue has been with implementing the element and having the code run. I have troubleshooted to exhaustion, and have brought my system down to 2 nodes, with an MVLEM element between the two nod...

Hi Frank, I am also interested in using this element in my modeling and I am getting yet a different message: "ERROR -- element of type MVLEM not known" It's suggested (by recent forum postings) that the element simply has a problem with running, but this seems more specific than that. The...
